"One of the things we highlighted about Zirkzee when we did throw criticism was that we enjoyed his hunger and his desire. What Ruben Amorim has managed to do is pull out the bits of his ability that suit Amorim's game the most.
"We have seen flurries of that throughout certain fixtures and we are like: 'Zirkzee might not be a waste of all this money after all because he's done really well there and I enjoy him'.
"You have to have characters like that in your team because they're hungry. I look at Rasmus Hojlund and I think: 'Is Hojlund hungry for a Premier League title?' I look at him and I think no, but I look at Zirkzee and I think he's got ambitions.
"He wants to be in winning sides - he wants to be at the top of his game."

Image source, Getty ImagesManchester United co-owner Sir Jim Ratcliffe said in his interview on Monday with the BBC's sports editor Dan Roan that some of the club's players were overpaid and some were underperforming.
Ratcliffe didn't single anyone out but was responding to a question in which Antony, Casemiro, Rasmus Hojlund and Andre Onana, amongst others, were mentioned.
Today was the first opportunity to talk about the comments with United head coach Ruben Amorim.
I didn't mention any of the players by name.
Amorim did.
"If we are being honest in this moment, everybody, me, all the players, we are underperforming this season," said the former Sporting boss. "We can always change that and I include myself in that part of the underperforming.
"You are talking about players like Casemiro, for example, that won everything and we know these kind of players can play so much better."
The former Real Madrid great is known to be the highest paid current United player but has been a major disappointment since his first season at the club in 2022-23.
Signed for £70m, Casemiro still has another year left on his contract and recently gave an interview in his native Brazil saying he would like to remain at Old Trafford.

Ruben Amorim has been speaking to the media before the second leg of their last-16 Europa League tie against Real Sociedad on Thursday (kick-off 20:00 GMT).
Here are the key lines from his news conference:
Amorim confirmed Manuel Ugarte will return to the squad.
However, the match comes too soon for Mason Mount, who was pictured training earlier on Wednesday.
Centre-backs Lenny Yoro and Harry Maguire are also unavailable, but Amorim "has hope" that the latter will be available for Sunday's match.
The United boss is impressed by the recently unveiled stadium plans, but added: "It is in the future - five years from now - so we have to focus on the present. I am really excited to win things at Old Trafford."
On Sir Jim Ratcliffe's comments about certain players underperforming and "being overpaid": "Everyone is underperforming - myself and the players. We can always change that and I include myself in that part of underperforming. He was honest on that, and the focus is to change his mind. In training, I feel they [the players] want this really bad."
Amorim said he has a "really good relationship" with the club's co-owner: "We are honest with each other. We have simple, clear and honest conversations. To give me support publicly is really good for a coach. Since day one, I have felt the support from everybody."
He said there is a "clear plan" in place for next season: "We can still reach the Champions League, so you never know. It can change the preparation for next season. We have a plan and we know what to do, in terms of what type of players to bring in."

Image source, Getty ImagesManchester United wing-back Patrick Dorgu says he has enjoyed life so far at Old Trafford.
The 20-year-old is still serving his Premier League suspension after his red card against Ipswich last month but will be available for selection for Thursday's Europa League last-16 second leg against Real Sociedad.
He said that his new boss Ruben Amorim was an important part behind his decision to join United in January.
"I saw Ruben at Sporting before he came here and I could already see the ideas he had," Dorgu said. "It's a very attacking system. I like to get in the box and score goals and also defend.
"He [Amorim] has been talking to me about the connection with other players, the midfielders and the number 10s. [He wants] a lot of deep runs and movement.
"I have settled well in Manchester. The training has been good and I'm getting on well with the team."
The Dane's versatility was part of his attraction to the United manager but Dorgu said he does not mind where he is deployed.
"I don't have a preference," he said. "It's the boss that makes the decision and I am comfortable playing on both sides."

Image source, Getty ImagesManchester United midfielder Mason Mount was involved in the open section of training before Thursday's Europa League last-16 tie with Real Sociedad at Old Trafford.
The £55m signing from Chelsea has endured a second injury plagued campaign.
He has started just four league games and has not featured since injuring his hamstring against Manchester City on 15 December.
Manuel Ugarte was also involved after missing two games with a 'knock'.
However, defensive pair Harry Maguire and Leny Yoro were both missing.
Realistically, United need to win the Europa League to qualify for European football next season. They drew the away leg in San Sebastian last week and are likely to play French club Lyon if they get through.

Image source, Getty ImagesChristian Eriksen admits it is "not fun" to look at the Premier League table and acknowledged Thursday's Europa League clash with Real Sociedad is "massive" for Manchester United.
United produced one of their most effective performances of the season in Sunday's 1-1 draw with Arsenal, even though head coach Ruben Amorim is uncomfortable with the counter-attacking approach.
However, it still left them 14th in the table. With 10 games of the campaign remaining, United are eight points off Fulham, who are 10th.
Any chance of qualifying for European football next season through their league position has virtually disappeared, which means United have to win the Europa League.
As they did against Arsenal, Amorim's side drew their last-16 first-leg encounter with Real Sociedad after taking the lead. Now they have to beat the Spanish side at Old Trafford on Thursday to reach the last night.
"It's massive," said Eriksen. "We know the pressure because we know the situation we are in.
"To get into Europe next season we have to win a lot of games in the league or go through the Europa League."
Only once since English clubs were allowed back into Europe in 1990 following their ban have United failed to qualify, in 2014 under David Moyes.
Unless their present situation improves they are heading for their worst league finish since the 1973-74 relegation campaign.
"It's not fun," said Eriksen, when asked what it is like looking at the table.
"We want to be higher. We are at (Manchester) United so we have to be higher. Hopefully at the end of the season we end up higher and we can forget about this but at the moment we have to fight for it."
Image source, PA MediaOn the latest episode of BBC Radio Manchester's The Devils' Advocate podcast, presenter Gaz Drinkwater spoke about thousands of United fans protesting against the club's ownership on Sunday:
"It was a big protest and it's United fans putting out the message about the Glazers and they want the full sale of the football club. I know they're frustrated at ticket prices as well, and what Ineos and Sir Jim Ratcliffe have done since they've come in.
"However, and this is the sad thing - and this isn't me saying there's no point in protesting because there's always a point in making your voice heard, no matter what it is - we had these protests in 2005. A load of blokes went and set up their own football club in 2005, who are still going strong to this day. There were bigger protests in 2009.
"There were protests again the other year when some United fans broke into the stadium and got the biggest game in English football called off - I know it was behind closed doors and I know there was the Super League surrounding that - but nothing changed.
"I know it's really sad to say it, but the Glazers don't care. They don't care about the average Manchester United fan, they don't care about those kids who were on that peaceful protest the other day with banners saying 'Save my football club'. They don't give one iota of a thought to those fans."

Manchester United have announced plans to build a new £2bn stadium over the next five years.
You can find reaction from key figures, experts, fans and more on the page below.
In summary:
Sir Jim Ratcliffe said the new ground "will be the world's greatest football stadium".
Sir Alex Ferguson stressed United "must be brave and seize this opportunity".
The head of the architecture firm overseeing the plans - Lord Norman Foster - said the stadium will be "the beating heart of a new sustainable district".
But fan groups were torn, with Manchester United Supporters Trust stating it will show "caution" while questions are answered and the 1958 fan group stating the new design was a "soulless corporate structure, more akin to a modern entertainment venue than a football cathedral".
Read what fans, key players and BBC Sport readers had to say below.
The Football News Show: Manchester United unveil new stadium plans
Image source, Foster + PartnersManchester United chief executive Omar Berrada has been answering questions following the club's announcement of plans to build a new £2bn stadium.
How do we go from the club running out of money to a new £2bn stadium?
The way the club was tracking, with all the losses that have been accumulated - more than £300m in the past five years - was not sustainable. So all the plans we've been putting in place over the last months really address the short-term issue, which is that the club was losing money.
Once we stop losing money, we then put ourselves in the best financial position to continue investing in our team and also to allow us to be able to have the ambition to build a new stadium.
Arsenal and Spurs weren't competitive while or after building new stadia - is there a danger that you can't deliver the stadium and a world-class team?
That is a risk. Clearly it's something we want to avoid.
We don't want to inhibit our ability to invest in the team, for us to continue being competitive while we are building a new stadium.
There's various ways around that and one of the things we are looking at is to shorten the construction timelines so we can have a new stadium within five years. That's our ambition.
In the meantime, by getting our finances back in order and becoming profitable, we believe that we can be very competitive.
The big, big benefit that this club has is that it has the biggest fanbase in the world and therefore the ability to be the number one in terms of revenues that it generates.
Could this project unlock the future for the club to be the richest one in the world all over again?
It's clear that our ambition is to have the best team in the world with the best stadium and most iconic stadium in the world. We want to have some of the best players in the world playing in front of our fans.
Our fans deserve to see a team that they can be proud of, that they can connect with, and to be able to do that in an amazing venue, like the one that we've shown today.

Image source, Getty ImagesThe group that organised protests before Manchester United's game against Arsenal have criticised the club's new "circus-like" stadium design.
United revealed plans on Tuesday to build an "iconic" £2bn 100,000-capacity stadium close to their current Old Trafford ground.
On Sunday, thousands of fans joined the biggest anti-ownership protest since Sir Jim Ratcliffe took a near 30% stake in the club, singing against the Glazer family and Ratcliffe, with reference made to the recent £66 ticket price rise.
In a statement following the stadium announcement, The 1958 group, who arranged the protests, said: "Manchester United's new stadium design fails to reflect the club's deep-rooted heritage, traditions, and connection to its supporters.
"Instead of embodying the gritty, historic essence of Old Trafford - a fortress built on generations of passion, emotion and belonging. The design resembles a generic, soulless corporate structure, more akin to a modern entertainment venue than a football cathedral.
"Its circus-like aesthetic disregards the club's working-class origins and the identity of a fanbase that spans generations. Rather than honouring the past and strengthening the bond with the local community, it prioritizes spectacle over substance, alienating those who have defined United's legacy for decades.
"It's an events stadium over a football stadium. It's a visitor experience over fan opinion and needs.
"Football, dignity and traditions need to be upheld and from what we can see they aren't.
"It should be a cathedral for fans to go and worship our team and not a circus like tourist attraction.
"Once again football taking a backseat."
In a wide-ranging interview with BBC sports editor Dan Roan on Monday, part-owner Ratcliffe talked about the financial difficulties the club has had having implemented a number of cost-saving strategies.
In their statement, the fan group also went on to question if any consultation with supporters had taken place and who would be funding the estimated £2bn stadium.
