Andre Villas-Boas' men have lost their last three Premier League matches.
Big Sam said: "At the moment we have the team to get a result wherever we go.
"They've still got the flair there and we have to cope with that flair on Sunday.
"It is difficult to produce the same level that you did in Europe so that's always difficult for a manager. I will be telling the players 'look, Tottenham played on Thursday and that may leave some physical fatigue'.
"If we are in the game going into the last quarter then we could come through in terms of how fit we are and get something out of the game."
