Portuguese football expert Tom Kunderton Ruben Amorim: "He's a fantastic communicator, so he gets his message across to players. You can even see it when he talks to the press, in his press conference, people are almost hanging on to every word that he says.

"He's a little bit similar to [Jose] Mourinho in that sense of his charisma, although he has a very different personality to Mourinho. He's always jovial, very polite, answers the questions calmly.

"I think he'll make a big impression in England. He's coming into a club that is comparable to how he came into Sporting, a sleeping giant, you could say."

At 39 years old, Ruben Amorim is Manchester United's youngest manager since a 31-year-old Wilf McGuinness became the permanent successor to Sir Matt Busby in June 1969.

BBC Sport chief football news reporter Simon Stone: "Manchester United's chief executive Omar Berrada went to Lisbon on Monday to try to negotiate. Amorim has a 30-day release clause in his contract and United were hoping to negotiate Sporting down from that. They have managed to do that in some sense but they would have wanted him quicker.

"Sporting wanted him to stay in charge for the Champions League game against Manchester City next Tuesday and a key league game [against Braga]. Sporting want to make a bit of a statement that they are not being pushed around. Manchester United have agreed to this.

"Ruud van Nistelrooy will be in charge for Chelsea on Sunday, the Europa League game against PAOK on Thursday and then Leicester at Old Trafford next Sunday. After that we don't know what will happen to Van Nistelrooy but we do know that Amorim will join as manager."

Dave, Morecambe: Re: Neil, Reading 9:40 - We always hear the phrase '...someone who knows the club.' Did Pep know Man City? Did Klopp know Liverpool? Did Emery know Villa? I could go on. History shows 'knowing the club' is usually a recipe for disaster. See Souness at Liverpool, Dalglish at Liverpool c.2011/12 and Ole at Man Utd.

Gary, Oxford: That has to be a joke from Neil in Reading, right? Right?!? Ole Gunnar Solskjaer, Neil. Remember him?

Ben: All well and good, Neil, but didn't the fans also know and love Solskjaer, arguably even more so? And what about Mourinho? Getting a suitable manager at United has become a lottery, but in most ways that's because of the dreadful running of the club by the people above (including recruitment and wages etc), and the manager bears the brunt.

Portuguese football expert Tom Kunderton what Ruben Amorim is like as a manager: "If he has anything like the impact and success he's had at Portugal, he will be a huge success at Manchester United. You can't really overstate or exaggerate what he's done here with Sporting, when they were an absolute mess, they were a complete chaos. They'd gone through three or four different managers [in quick succession] prior to his appointment.

"They were completely in the shadows of Benfica and Porto and he completely turned around the club in his first full season. The next season [they were] very close to winning the league again and last season came roaring back. I'm pretty certain if he stayed, Sporting would win the league again. He's had a huge impact on Portuguese football."

Anon: Could not disagree with Ian @ 12.25 anymore, Gareth Southgate was exactly what this club didn't need, he would have had a similar reign to Moyes, short, ineffective and a style of play that doesn't fit the united way. United have done incredibly well considering where they're at right now to land Amorim in my opinion.

Ruben Amorim's trophies as a manager:

• Taca de Liga - Braga (2019-20)
• Primeira Liga - Sporting (2020-21, 2023-24)

Somebody had to get the job and that is the beauty of football. When Erik ten Hag leaves they have got to go and get someone else and they have chosen [Ruben] Amorim. It is a great club and a great job for him to have a good run at it. Maybe he is the right man but time will tell.

He comes in with a good pedigree and it is a different type of football. It is different to when Jose Mourinho came over and he became that great manager after success in Europe (Uefa Cup and Champions League with Porto).

This is a little bit different. The great thing he has got is he has a great club and fanbase behind him. Hopefully he is a big success because I think everyone needs to see Manchester United up there.

As translated via Google: "Sporting SAD has reached an agreement with Manchester United FC (hereinafter MUFC) regarding terms and conditions of coach Ruben Amorim's departure, in return for which MUFC will pay Sporting SAD 11,000,000 euros (£9,252,210)."

Ruben Amorim has had an impressive record with Sporting since arriving there from Braga in March 2020.

• Matches: 228
• Wins: 161
• Draws: 34
• Defeats: 33
• Win percentage: 70.61%

Prior to that, Amorim had short spells in charge of Braga, Braga B and Casa Pia, with a win percentage of 72% and above with all three teams.

Yesterday, Ruben Amorim said clarification over Manchester United's interest would come after Sporting's match against Estrela tonight.

It's come a little sooner with United's announcement, but we'll no doubt hear from the new United boss after that game.

"It's a massive, massive gamble, because of the state of the club right now."

On today's Football News Show, French journalist Julien Laurens assesses whether it is Manchester United or Ruben Amorim taking the bigger risk.

As Manchester United supporters prepare to welcome a highly-rated and talented coach from outside of Europe's 'big five' leagues who has analysts swooning, they may be worried that it all sounds a bit familiar.

But in Ruben Amorim, they can be certain that in one crucial aspect he won’t be anything like Erik ten Hag.

The defining complaint about the sacked Dutchman was that after two-and-a-bit seasons the football was still formless and the tactical direction indecipherable.

Amorim, who will leave Portuguese champions Sporting to move to Old Trafford next month, is nothing if not a diligent - and decisive - tactical thinker.

From a ruthless press to proactive possession football, from a daring high line to a complexly shape-shifting 3-4-3 formation, the hallmarks of Amorim’s football will be etched into muscle memory in detailed training sessions.

And there will be valid concerns. Most prominent will be how a Manchester United squad built in Ten Hag’s image will cope with the change to a back three and a tactical system entirely at odds with what came before. It won’t suit everyone.

With United posting a £113m net loss for 2023-24, a £15m compensation bill for sacking Ten Hag and paying at least £8m to trigger Amorim's release clause, added to the £200m spent on summer transfers, the Portuguese is not likely to have much budget for January signings.

Here’s a look at the biggest winners and losers from Ruben Amorim’s appointment.

Despite reports to the contrary, Manchester United officials are adamant the club did not speak to anyone else about their vacancy, having decided Ruben Amorim fits their structure, headed up by sporting director Dan Ashworth and technical director Jason Wilcox.

It completes the overhaul triggered by Sir Jim Ratcliffe’s part purchase of the club on Christmas Eve.

It is fairly obvious but United have focussed on Amorim’s style of play, personality, development of young players and energy as the key characteristics that make him suited to the role, although there is no suggestion Erik ten Hag lacked these qualities.

United feel they have recruited what club officials are calling "the most exciting young coach in Europe". Their optimism about the future has been familiar around all their previous managers post Sir Alex Ferguson.

This appointment is the first of the Ineos era. Club officials know after all the talk, Ratcliffe will take full responsibility for what happens going forward.
