We take a 2-1 lead into the fixture after goals from Roberto Soldado and Harry Kane turned around a 1-0 deficit in Larnaca last Thursday.
The winners progress to the group stage of the competition and with the prize for the winners a place in the Champions League next season, the stakes are as high as ever.
"It’s a very important game for us and we need to be focused," said Mauricio.
"It’s true we brought back a good result from the first leg but we need to win again.
"All games are different, and difficult. It’s important for us to follow our style and our system and try to win and not to think about the result in the first leg.
"So for me, it’s 0-0 and we need to try to win this game."
We kick-off at 7.45pm tonight.
