Fulham manager Martin Jol will look to strengthen his squad in January despite the difficulties posed by the upcoming transfer window.
The Cottagers enjoyed a good start to the season after losing Mousa Dembele, Clint Dempsey and Danny Murphy. Jol brought in free agents Giorgos Karagounis and Mickael Tavares after the summer window closed in a bid to beef up his side and there look set to be more new faces arriving in west London.
Jol said: "Of course we will always look to strengthen, but the January transfer period is not an ideal one. The good players will stay at their clubs or you can't afford them because clubs are asking too much money, but we will come up with something."
Unlike Pogrebnyak, who moved on to Reading, the Malian is still at Craven Cottage and Jol is having to plan for his absence in the new year.
Diarra's form at Fulham has seen him return to the national team set-up, meaning he may well soon be heading to the African nations Cup.
"We'll look to strengthen the squad because if Diarra goes I can do nothing about it," Jol said. "As it is now he will go to the African Nations Cup.
"He was so good for me last year because a lot of older players left the club. He changed the dressing room."
