The Gabon international has admitted a desire to play in England, and has been linked with a January move to the likes of Bolton and Middlesbrough.
"I've never won any medals in football before and I am keen to change that. That is why I came to Rangers and I am hungry to win silverware here.
"I am very happy here but if a better offer came in from somewhere, I would have to consider it. Any footballer would do that.
"Should such a situation arise, I would need to talk to the manager and the chairman about it.
"But I am pleased with things as they stand at the moment and I have no problems with staying at Rangers just now, none at all.
"Now I am only looking forward to the challenge ahead. We have some hard games coming up and I am determined we will win them and claim the title."
