Bryan Ruiz has urged Fulham not to dwell on their defeat to Southampton.
Ruiz knows they need to buck up their ideas if they are to avoid more disappointment, starting at the King Power Stadium.
"Southampton played well," Ruiz told the club's official website.
"We had a plan but once they scored the first goal it was difficult to find a way back into the match. They deserved the win but now we have to pick ourselves up and look towards the next match.
"After winning two games in a row, we wanted to continue that at Southampton. We weren't able to do it and we were all disappointed with the display.
"The most frustrating thing was not testing their goalkeeper. We should have done more but Southampton have only conceded three goals this season and they're very strong defensively.
"They are in good shape and full of confidence but we need to try and forget about it now and concentrate on the next match.
"We've got two games coming up quickly and it will be a tough week. We want to qualify for the next round of the cup and then take on Manchester United in a good frame of mind."
