Chelsea are prepared to sell Marcos Alonso this summer.

Atletico Madrid boss Diego Simeone is on the hunt for a new left-back after Lucas Hernandez joined Bayern Munich for £68m.

And fellow left-back Filipe Luis, who spent a year at Chelsea earlier in his career, will also leave the club.

It has been reported that Alonso is top of Simeone's wishlist this summer, with a bid thought to be imminent.

Radio Cope reports Chelsea would be willing to sell Alonso for €40m.
