A video has now emerged showing what Reece James did when Mason Mount was subbed on against Chelsea last night.
Posted on the Twitter of TNT Sports, the club captain can be seen in the background as the former Blue is introduced late on for Manchester United.
Chelsea fans were certainly not pleased to see Mount in what was his first outing against them since leaving over the summer.
Mount jeered by Chelsea fans
There was a mixed response to him warming up before the game got underway, however were quick to chant in his direction when they had taken the lead early on.
Fast forward to the last few minutes though, and it looked as if the England international was going to have the last laugh as his side led 3-2 with moments to go.
That was until Cole Palmer had his say late on, scoring twice in added time to turn it around, including the latest winning goal in Premier League history.
Mount was greeted by a predictable showering of boos at Stamford Bridge, although one Chelsea player seemed to show his appreciation.
