Blues no more is what Mason Mount will be next season, and fans were left frustrated and sad by the departure of the young player.

And Mount is feeling the same way.

The 24-year-old turned to Instagram to express his sadness about leaving his boyhood club.

He acknowledged his desire to leave the club had been known to supporters for six months but insisted that this move was more about him.

"I feel you deserve more than a written statement, so I wanted to tell you directly how grateful I have been for all of your support over the last 18 years," he said in the video post on his official account.

"I know some of you won't be happy with my decision, but it's what's right for me at this moment in my career."

Mount has agreed to join Manchester United on a five-year $70 million transfer fee after languishing on the bench last season.

He has been with Chelsea since he was six years old. He will leave the club as a Champions League, UEFA Super Cup, and FIFA Club World Cup winner.

Mount and Erik Tan Hag's connection

Mount wanted to leave Chelsea, and manager Erik ten Hag made his move to Manchester United easier.

Reports have revealed that Tan Hag approached the 24 years old and expressed his admiration for his playing style and how he would figure in the team's formation.

"Mount opted for United over remaining at Chelsea or joining Liverpool due to the strong pitch Ten Hag, who has followed him closely since 2018, made to him," per Sky Sports.
