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.
And while he admits he would listen to any offers that came his way, he is happy with the way he has settled since his £1million summer move from Lens.
"With Lens, we got to the UEFA Cup through one of the Intertoto Cup finals but that was when there wasn't a trophy for winning that," the 30-year-old told Rangers News.
"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."
