Defender Alain Goma has given his teammates a double warning about the forthcoming clash with Walsall in the FA Cup fifth round.
Goma said: "It will be a difficult game for us because it is such a prestigious competition and Walsall will want to win badly," said the French defender.
"They have already beaten Charlton and we have to respect them."
Goma is also warning The Cottagers not to get carried away with reports that they are one of the favourites to lift the trophy.
Having been drawn against First Division Walsall in the fifth round and with the likes of Manchester United, Liverpool and Leeds already out, Fulham are already dreaming of a repeat of the glory days of 1975.
But Goma says it is foolish to even think about reaching the final just yet. He said: "The best way to win a cup is not look forward. "You have to take it step by step.
"Our next match is Walsall and we have to be focused on that game and that round, there's no point in talking about being favourites or it will never happen."
