Chelsea have informed AC Milan they must pay top price for Tiemoue Bakayoko.

On-loan from the Blues, the midfielder has been outstanding for the Rossonero since the New Year.

Bakayoko arrived on loan for €5m with an option to buy at the end of the season for €35m plus €3m in bonuses.

And Chelsea are insisting Milan pay full price if they want to keep him, reports Sportitalia.

The Londoners paid €40m to AS Monaco two years ago for Bakayoko.
