Espanyol striker Wu Lei admits they'll use tonight's clash at Wolves to fine-tune ahead of Sunday's critical clash with Atletico Madrid.

Relegation-threatened Espanyol go to Molineux trailing 4-0 on aggregate for the second-leg of their round 32 tie.

Wu Lei said, "Tomorrow we will seek to win, because we are not satisfied with the last two games. We want to win and prepare well for Sunday.

"The result of the first leg is very tough, but we want to try. It's difficult, but we want to come back.

"Everyone was very disappointed after Valladolid, but the next day, everyone was talking, we are convinced of staying up."
