Former Manchester United striker Giuseppe Rossi is on loan at Celta Vigo this season but he ruptured his cruciate ligament two weeks ago and therefore cannot play.
It will be a first
For the second semi-finalists - Celta Vigo have never played Man Utd before. Celta beat Liverpool home and away in 1998 and Villa too in the Intertoto in 2000 but lost against Arsenal home and away in the Champions League in 2003-04.

in the first leg.
Ajax will play
First out of the bowl are
Right we're off
After best wishes are conveyed to Zlatan Ibrahimovic.
And to make the draw ...
Is 2001 Champions League winner Patrik Andersson, the Europa League final ambassador.
It's the return of Giorgio Marchetti
Which signals there are only five minutes' procrastination to go ...
Is the president of the city council of Stockholm to welcome the final to her home town, the first in Sweden since 2004's final in Gothenburg. She notes that Zlatan scored four times against England in the inaugural Friends Arena fixture and hopes he will be fit soon. She also pays tribute to the victims of the terrorist attack in Stockholm and hopes to celebrate open societies.
Here we go
And it's Pedro Pinto again as host. You'll know him from The Game podcast and CNN before he joined the Uefa gravy train.
The semi-finals will be played ...
On Thursday, May 4 and Thursday, May 11, giving supporters based in England - no assumptions here, they could be Celta Vigo fans from Featherstone - only 13 days to sort accommodation, commandeer fishing smacks from Hull or the ferry from Immingham. Sadly the Newcastle-upon-Tyne service to Gothenburg is no more.
And welcome to coverage of the Europa League semi-final draw from Nyon which will begin shortly after noon, probably after we've been treated to this anthem, all a bit Knots Landing to the big-eared Cup's Dallas.
And the names in the pot today are last night's succesful sides:
Only Ajax have won it before (in 1992). In fact only Ajax have been finalists before so it will be virgin territory for at least one of the three other sides if they take the field at the Friends Arena in Stockholm on May 24.

Which teams are left in it?
Are Manchester United favourites to win the competition?
They are. It's likely the Europa League will be United's only chance of qualifying for the Champions League next season.
Manchester United remain on course to win the Europa League for the first time in their history after a nervy win over Anderlecht on Thursday evening.
Marcus Rashford scored the all-important goal in extra time to ensure a 3-2 aggregate win for Jose Mourinho's side.
Despite sitting just four points off fourth place, Jose Mourinho has already confirmed winning the Europa League is his number one priority.
“It is the only chance we have to win one more trophy,” said Mourinho, who has already lifted the League Cup in his first season at Old Trafford.
“It is as difficult as finishing fourth, but it is the only competition that we can win now, so we have to fight for that.
Sir Alex Ferguson echoed Jose Mourinho's words insisting the club should focus all their energy on winning the competition.
"The thing is, we've never won the Europa League," he told ESPN.
"We've never won Uefa Cup, what it used to be. And we've got a great draw. I'm not saying it's a certainty, but they've got a great chance.
"It's still a European trophy. And if you win it, you get into the Champions League. The incentive is greater to do that."
“I don’t want our club to be just happy fighting for top four and Champions League. I want us fighting for trophies.
“We don’t hide that we are still fighting for our situation in the Premier League but the Europa League becomes a fundamental competition for us. The Premier League was not possible because we drew too many matches.”
What are the latest odds?
- Man Utd - 23/20
- Lyon - 3/1
- Celta Vigo - 6/1
- Ajax - 7/1
