Wolverhampton Wanderers manager Nuno Espirito Santo admits his side will have to put their holidays on hold.
The Premier League club pushed through into the quarter finals of the Europa League, defeating Olympiacos 1-0 to progress 2-1 on aggregate.
Raul Jimenez got an early penalty goal to give his side the advantage, which they never looked like squandering.
Nuno told reporters after the game: "I told the boys, 'OK our holidays must wait. We will have them, but not now'. It was the last game at Molineux this season, we miss our fans, it's not the same but the boys must be proud. Let's hope we are together again at Molineux.
"We started with Crusaders a long time ago, more than a year ago. Everyone has to realise that it's been a long, long season. We've had a fantastic victory which allows us to be in the last eight, it's huge.
"I don't know how many miles we've travelled, it's crazy. That's what I said to the players. Football gives us good moments and bad moments but it's also enjoyable to compete.
"Now we will rest and we'll focus on Sevilla. We are going to face a very good opponent. It's going to be tough but let's make this final effort. It's challenging ourselves."
