Chelsea and Brighton’s discussions over a deal for Moises Caicedo have stalled due to disagreement over Levi Colwill’s involvement, the Guardian reports.

The Seagulls are demanding no less than £100m for their 21-year-old midfielder, unless as part of a swap deal including Colwill, after the 20-year-old defender spent last season on loan at the Amex Stadium.

However, Blues head coach Mauricio Pochettino has Colwill, an England under-21 international, in his plans for next season and is unwilling to let him leave Stamford Bridge this summer.
