Manchester United legend Rio Ferdinand has claimed Chelsea will regret selling Mason Mount to Manchester United.

Manchester United will pay £55m plus a possible £5m in add-ons for Mount who has penned a £250,000-a-week contract at Old Trafford until 2028 with the option of another year.

“Really pleased with Mount coming in,” Ferdinand tweeted. “Young, talented and hungry. He has the experience of big games with pressure which comes when playing for Utd.

“As a player he will bring us goals, creativity, a work ethic and a willing runner into the opposition box.

“He definitely adds to what we have in the squad and is different from the others in midfield.”

Ferdinand continued: “I actually think in time Chelsea will regret selling Mount. Now for a No.9….”
