Sassuolo coach Roberto De Zerbi says Jeremie Boga should stay with them next season.

The former Chelsea wing-back is interesting the Blues, which boast a buy-back option, and also Barcelona.

But De Zerbi insists Sassuolo remains the best place for Boga.

"He is a footballer who certainly has ample room for improvement," he said.

"He needs to stay a few more years at Sassuolo."
