The Cottagers boss has commented on his side's shock 3-0 home loss on Saturday after they were dominated by the Welsh side's slick-passing style of play
A Gylfi Sigurdsson double either side of the break put the visitors into a comfortable position, with a Joe Allen effort ten minutes from time sealing the win for the Welsh side.
Jol believes that last week's defeat at Aston Villa didn't play too big a role in the way his side performed against Brendan Rodgers' team, insisting that confidence in their home form was separate from when they play on the road.
"If you play six games at home without a defeat, your confidence at home is probably bigger than away; our intentions were good, but we couldn't do what we always do.” he told reporters.
“We gave them more belief and strength, and they took advantage of that.
"I thought that in the main you could say, especially at home, we've got a lot of players with good performances and today we didn't play like a team. All the players that normally make a difference were not there.”
Fulham are currently 11th in the league with 36 points, having been leap-frogged by the high-flying Swansea City. Rodgers' side are now in eighth after enjoying a number of high-profile wins against the likes of Manchester City and Arsenal in recent weeks.
"It was a challenge. They are on similar points to us, they've had a great season and we haven't done that badly so far.
"It was important for us to get a home win today and get to 39 points and try to get up to maybe 50 points. But of course now we have to go to Man United and pick ourselves up and try to do better than we did today.
"We saw them play three or four times and a couple of teams decided to take the game to them and did well.
"Until last month they didn't really win away games, only in the last three or four games away from home they've done well. But they play their own style so we tried to restrict them but we couldn't."
