Diarra said that all the Whites players are aware that they have to win at the Britannia and is confident that there is enough in the squad to be able to take the three points.
"I know the importance of the game," he told the club's official website. "We all know how crucial it is to the club surviving in the Premier League. "If we want to enjoy our summer holidays we can only do it by staying up. No-one wants us to be in the Championship.
"We are going to play against one of the stronger teams in England and it won't be easy. It's going to be a tough game but we are ready for it. We know what is waiting for us there and we'll approach the game like warriors. With a strong determination and winning mentality, we can get something there.
"It will be a battle but we are prepared. We are not scared. It's true there is a lot of pressure on us, but we can do something there – and we have to."
Fulham are currently 19th in the Premier League with 31 points.
