The 34-year-old Ivory Coast defender's contract ends in the summer and he wants first team football.
"It's been a difficult season for all the team and everyone at the club as we haven't done as well as last season," he said.
"For me, there's a decision to be taken. I am looking around and seeing what's best for my family.
"I'm talking with my wife to see what that decision will be. I'm a competitor and I want to play more."
