The Spaniard, who spoke at a pre-match press conference on Monday, also called on his side to remain 'focused' against the Premier League outfit.
"I'm expecting a very even game. Our opponents have a very clear way of playing. It's going to be very physical and tactical," said Garcia.
"Our job is to stay focused. We know this is such an important game and the team is prepared for that.
"There's lots of rumours and speculation in the press, just as there is out in the street, but all we'll focus on is our game."
The first leg will take place at the Vicente Calderon.
