The Cottagers face the Polish champions without captain Danny Murphy, Clint Dempsey and Bobby Zamora.

The latter pair have been rested ahead of Sunday's Barclays Premier League match against Everton, while Murphy misses out with a knee injury - but Jol remains confident of victory at the Stadion Miejski and backed his squad players to rise to the occasion.

"Danny took a knock to his knee, which was pretty painful but hopefully he will be fit for selection on Sunday," the Dutchman said.

"I spoke to the medical staff and we decided not to take a risk.

"Dempsey was left in London and Bobby was the same as I want him for Sunday rather than risking him tomorrow because we have got Andrew Johnson.

"[Mousa] Dembele is with us even though he had a little problem with his ankle and we have Orlando Sa, who can also play in attack.

"We took a few younger players instead, like Kerim Frei, Alex Smith and Marcel Gecov.

"That said, I do not have any concerns before the match. We have played with different teams before and have 22 good players, as well as a few younger players.

"Overall, we still have a very strong team."

Wisla manager Robert Maaskant is hoping to outsmart countryman Jol and overcome a poor start in Group K, which has seen the White Star lose both their matches and concede seven goals.

Despite having suffered heavy losses to both Odense BK and FC Twente, Maaskant thinks they can turn the corner tomorrow.

"The plan is, like always, to score one more goal than they do," said the Dutchman. "That is plan one.

"Of course, we know Fulham are a very good side.

"It has not been very easy to analyse Fulham because they have been changing their line-up many times over the last eight games.

"There are always five players that start but other than that we don't know, for example tomorrow with Dembele because he had a little injury against Stoke.

"So we are not sure how they are going to play but we have to have our own plan.

"We are not going to change that much because it is not possible to change a whole system or to play totally different.

"Of course we are aware that the result tomorrow is going to be very important for the rest of the games.

"We hope are smart enough to get a result against maybe a stronger team."
