The Cottagers have slipped into the bottom three and are two points from safety ahead of today's home game against Southampton.
"It is a real dogfight but we are up for it," said the Fulham captain.
"Like any game now, tomorrow is vital. We were hoping to get something from Swansea on Tuesday but we lost and, as a consequence, the game tomorrow is even more important. It is not going to be an easy game but we need to get something. I am very confident that we have enough in the side [to stay up]."
