Players are out everywhere and it's almost time to go.

Since the Europa League was set up in 2009, only one side have lost a first leg by two goals at home and gone through.

That was in 2014 when Sevilla beat local rivals Real Betis on penalties with both legs ending 0-2.

The winners of Villarreal and Dinamo Zagreb will face Arsenal or Slavia Prague in the semis.

Villarreal won the first leg 1-0 in Croatia.

"We know how Dinamo Zagreb like to play and if you let them link up or hit you on the counter, where they're quick, they can do you damage," Villarreal's former Arsenal boss Unai Emery said.

Dinamo coach Damir Krznar said: "We still have a realistic chance, the recipe is how we played in the first half. I think we are still in the tie."

Roma beat Ajax 2-1 in the first leg in Amsterdam. The winners of this tie face Manchester United or Granada in the semi-finals.

Roma boss Paulo Fonseca said: "It might be the most important game of the season so far. We know we need to play a perfect game again in order to progress."

Ajax counterpart Erik ten Hag said: "The result might not be on our side, but we are optimistic. There is absolutely no difference between playing home or away, we’ll face the game with that spirit."

Arsenal may not have missed a European campaign since 1995-96, but Slavia Prague are looking to reach a first semi-final in continental competition in that time - it is 25 years since they made it to the last four of the Uefa Cup before losing to Bordeaux.

The Czech side have lost just one of their last 10 European games (W6 D3), after losing six of their eight before that (including qualifiers).

CM: Arteta is a 2021 Spanish reboot of Steve McClaren. I mean look at that formation & selection tonight... nice guy, maybe a good coach, but a bang average manager who making bizarre tactical choices in an attempt to look decisive. "This is so crazy it just might work!"

What do you reckon Bruno Fernandes and Paul Pogba are talking about here?

"No, Paul. I'm taking the free-kicks tonight," is our bet.

Slavia Prague will be without Ondrej Kudela, who has been banned for 10 matches after racially abusing Glen Kamara. The Rangers midfielder was also suspended for three games.

The Finn has been found guilty of assaulting Kudela in the tunnel after their Europa League meeting at Ibrox in March, which Slavia won 2-0 to claim a 3-1 aggregate victory.

Kamara's lawyer, Aamer Anwar, called Kudela's sanction "the barest minimum penalty" and made "a mockery of Uefa's claims on taking racism seriously".

He also suggested Kamara's suspension was reduced from five games on appeal.

Arsenal

Arsenal boss Mikel Arteta, speaking to BT Sport: "We are really excited, we want to be in that semi-final and our approach and energy is just towards the game.

"Emile Smith-Rowe is fit and ready to go, so good news.

"I did like it (the system in the win over Sheffield United) but it also fits the requirements of the game, we kept a clean sheet which is important.

"We need to improve our efficiency with the amount of chances we created in the first leg, today we need to score a goal at least and we must do better."

Arsenal boss Mikel Arteta say he is aware his tenure at the club will be judged on results, with the Gunners potentially facing the prospect of the club's first season without European football since 1995-96 next term.

"Tangible is the right word and the only tangible thing is results," he said. "Whether you're doing a good job or not, to judge it externally is only going to be judged with results.

"Internally, you know what you are doing and you can have many different ways of judging that but at the end of the day, externally results are the only important thing to give the perception that we are moving forward in the right direction."

Of all the players still involved in the 2020-21 Europa League, only Roma's Borja Mayoral, with nine, has been directly involved in more goals in the competition this season than Arsenal's Nicolas Pepe, who has four goals and three assists.

Arsenal know they will have to be switched on until the final whistle tonight.

Mikel Arteta's side were sitting on a 1-0 goal advantage in the first leg when Slavia Prague scored a dramatic stoppage time equaliser to suddenly claim the away goal advantage heading back to the Czech Republic.

Tomas Holes headed home in the dying moments of the game from close range to give Slavia Prague a precious away goal.

Former Arsenal and England player Karen Carney: "It was a nightmare for Arsenal, absolutely devastating. Arsenal had a lot of chances, Slavia Prague should have been dead and buried."

Former Arsenal and England defender Martin Keown: "It was about Arsenal and the way they played and by sitting off, I thought they chose the wrong tactics. It's a disastrous result but it's not the end."

The change was in place for the last home game against Brighton but just to emphasise, this is what Manchester United have done as part of an anti-racism initiative.

Sir Alex Ferguson employed an eye coach during his time at Old Trafford in the search for marginal gains.

Was it a problem? I don't know - but if it stops players thinking there is one, it is probably a good decision.

United are unbeaten in their past 16 home games in the Europa League, winning five in a row before the draws against Real Sociedad and AC Milan this year.

They have been successful in all 21 European ties in which they won the first leg away from home.

Granada boss Diego Martinez: "We trust in our possibilities to do well. When you go out with a determination you can do anything and that includes the game tomorrow night.

"We believe in ourselves. Someone has to win the game and we trust our own players. As a minimum, that's the least you can do, isn't it? Believe in yourselves totally.

"When we were handing over our passports at the airport, the police at the airport were thanking us for all we've achieved.

"We never imagined that we'd be even in the first division many years ago.

"This team, what they've managed to achieve, are things which were almost impossible to consider in years before and so we're convinced about our chances.

"We know we're up against a magnificent opponent, a really tough opponent, but we're going to go for it with determination and we'll be trying our best."

Man Utd left-back Alex Telles: "I have quality. I feel I can fit in. I am happy for Luke. He is a great player. If everyone is playing well and there is competition for places that is good for the club.

"Here in England, it is more raw and tough but I am more settled in. I feel like I am ready for everything and to feature whenever.

"I would love to be able to take more free-kicks and have more assists. That is what we work on in training."
