Fulham boss Martin Jol has called on his out-of-contract stars to show mental strength and commit their futures to the club.
Skipper Danny Murphy and Andy Johnson are both free agents in the summer, while Clint Dempsey has one more year on his present deal.
Progress on new deals has been slow so far, but with Fulham's top-flight status virtually secure, Jol hopes negotiations will become easier.
"If they are mentally strong they will stay with us," said Jol.
"If not, if they need to play or go somewhere else, we can go on with our transformation.
"We have five or six players who are different from last year but we are not there yet.
"The balance could be better at times and I want us to be a bit more aggressive at times.
"There are goals in us but for the last five or six years Fulham has not scored enough away from home, which is strange."
