Fulham boss Martin Jol admits he's delighted with his form of Clint Dempsey.

Fulham face Everton on Friday night in the FA Cup fourth round, where Dempsey will face fellow United States internationals Landon Donovan and Tim Howard.

The latter suggested in the build-up to the match that the west Londoners are increasingly relying on Dempsey's presence, although Jol downplayed the comment.

"It is always great to have players that can make the difference and he (Howard) probably does that for Everton as well," the Dutchman said.

"You always rely on good goalkeepers, good centre forwards and productive players.

"You will never be a good team without one or two players [that can make the difference].

"Even Barcelona would not be without players that can make the difference and Clint did that.

"We have other players that can score. We have got goals in us, with Bryan Ruiz, Mousa Dembele and Bobby Zamora, who was involved in at least three goals the other day.

"We have got the quality but I can't deny that Clint was very different for us this year.

"Maybe he was in the past. I think so because he was our top scorer before.

"You always like your top scorer to be up front but if it's Clint, it's Clint. If it is Bobby, it is Bobby. It doesn't matter to me."
