Manchester United have given Chelsea a huge wakeup call regarding the potential sale of Mason Mount this summer. The 24-year-old midfielder faces an increasingly uncertain future at Stamford Bridge, with his contract expiring in 12-months.
football.london understands that the Blues were once close to reaching an agreement with Mount over a new deal but, upon his return from the World Cup in December, an offer was no longer on the table. Towards the end of January, the west Londoners reopened talks with the England international, though he didn't want to sign a one-year extension.
It's understood that Mount has not received another proposal since then, meaning that he'll become a free agent at the end of next season. football.london understands that United, Liverpool and Arsenal are all seriously interested in signing the Cobham graduate, who looks set to leave Chelsea this summer.
