Fulham have not won any of their last seven league matches and have slipped down the table to just four points above the relegation zone.
They have not scored a goal for 298 minutes and welcome Newcastle to Craven Cottage on Monday evening.
Their most recent victory came on October 20 and manager Jol said: "We have to pick up ourselves and pick up some points.
"Even in the first half against Spurs we had three or four chances which as more than they had, and more attempts on goal.
"Against Sunderland, for example, before Brede Hangeland's red card, I thought we were the better team.
"That was probably the biggest disappointment because those three points would have given us 20 points.
"It all started on that day. We got injuries to Bryan Ruiz and Alex Kacaniklic so after that we had to change things and I feel we are good enough to come up with a solution.
"Three weeks ago we were all very happy at Fulham and two weeks later the situation totally changes."
