Chamakh now views the game at Emirates Stadium as a remedy for Arsenal's Wembley heartache.
"On Monday morning we had training, on Wednesday we play again and we have the chance to bounce back," the Moroccan told arsenal.com. "We have all had a bad night but we will bounce back.
"We are lucky to have another game to play as soon as Wednesday. We need to think about that game, focus on it and not think about this final.
"We need to forget what happened today and make sure the defeat doesn't stay on our minds. We still have a lot of big games and challenges to play and we will fight on until the end of the season."
