The White Star have performed miserably in their two Group K matches so far, conceding seven goals in two defeats.
Despite having suffered heavy losses to both Odense BK and FC Twente, Maaskant thinks the Polish champions can turn the corner on Thursday against Jol's side.
"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 [Mousa] 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."
