The striker went AWOL on deadline day when he flied to France in an attempt to force a transfer to Ligue 1 side Rennes. Despite passing a medical without the club's permission, Slaven Bilic has since brought Sakho back into the fold this season.
There has been talk of a contract extension, but after a move in the summer failed to materialise, the forward is desperate to leave. "I still want to leave. I always say it. I don't hide it," Sakho told Belgian journalist Claude Atcheba.
"Whether the fans are happy or not, I want to change environment. I want to see something else in regard to everything happened to me. I think going to France would be good to find a challenge for my career," he added.
"If I don't sign somewhere else it means I have to come back to my club. And today I'm happy to be here. After, I have been booed during games. The fans are unhappy with me, that's normal," he said. "I have nothing against the fans, players or the manager. But nobody convinced me to stay."
