Salomon Kalou has put several Premier League clubs on alert by admitting that he is unsure as to whether he will be at Lille after the January transfer window.
The former Chelsea forward moved to France in the summer but has yet to make a real impact in Ligue 1, scoring just three times in 18 appearances.
Queens Park Rangers, Everton and West Ham United are all understood to be ready to offer Kalou a return to England and although the Ivorian feels that he is settling at his new club, he has confessed that he does not know what his future holds.
"I do not know if I will leave in this window. I have a four-year contract with Lille. I am settling," he told Sky Sports News.
"They have a great coach who has faith in me. He wants me here and I want to be here and play week in, week out - which I was not doing at Chelsea."
Kalou's Lille contract runs until 2016.
