Former England striker Ian Wright has suggested that Chelsea should sell Diego Costa in January if they can find a buyer.

The 27-year-old has failed to replicate his form from last season, and Wright believes that the club do need to buy a striker in the winter transfer window if they want to make the Champions League places.

Wright told BT Sport: "When you look at their squad, I do not think they do need any new signings but something's happening in there where they are not functioning like they used to.

"If I was in, if I could get a striker then I would get one. What do you mean you do not need someone? I said that if you could get rid of Costa if I could in January.

"If he could get someone like [Edinson] Cavani and get Costa out, I would do it."

Costa has scored three goals in 14 appearances in all competitions so far this season.
