Mason Mount is now officially Manchester United's first signing of the summer transfer window.
The 24-year-old has signed for United for a £55m initial fee from Chelsea, which could rise to £60m due to performance-related add-ons. Mount was in the final year of his contract at Stamford Bridge and United have moved to add to their midfield department with the England international's services.
Mount underwent a medical at United's Carrington training ground earlier this week and now the club have officially announced his signing.
