The former Republic of Ireland winger (left) is among a number of Fulham stars with deals ending in the summer but Jol insists he is keen to add, rather than take away from his squad.
"We are not in a situation where we can do that (let players go)," he said. "With the other players (in the summer) we had to sell them because of clauses and other problems.
"But I would love to keep my players as it is. For next season it's another matter and we feel we will keep the players we want to keep."
