Chelsea prepare Marc Cucurella swap deal as Brighton star ‘wants to join’ Blues

Chelsea, meanwhile, could be about to let Marcos Alonso join Barcelona. Cucurella would be a replacement for his fellow Spaniard and provide competition for Ben Chilwell at left wing-back.

Blues youngster Colwill impressed while on loan at Huddersfield last season. The left-footed defender, who can play at centre-back and left-back, has been linked with a permanent move away from Chelsea.

Express Sport understands Brighton are big admirers of the 19-year-old. Colwill has been at Chelsea since under-9 level but is yet to make a senior appearance for the club.

Tuchel spoke about Colwill last month and assessed his chances of being given an opportunity in the first team this season. He said: “Simply, I haven’t seen enough of him in our group because unfortunately he got a little injury and was out of training for several days.
