The Cameroon international has started just 14-games this season, despite their struggles with injury.
Sebastian Bassong: "I admit I am disappointed.
"I was a regular last season but this season I have spent a lot of time on the bench.
"It hurts being constantly overlooked. If I'm not playing for Tottenham, then maybe I am not much use to them.
"I want to stay but if you are not playing, you have to consider your options. It would be irresponsible not to."
