Manchester City defender Kolo Toure says they must not dwell on their Europa League elimination at the hands of Sporting Lisbon.
"It was important to win this game and go through, but now we need to keep our heads up," he said.
"We have a really important game coming up on Wednesday against Chelsea and we have to give it all.
"For Man City now every trophy is very important so when we go out like that, it is always very difficult, but now we just need to think about the future. The past is the past."
