The Sun reported that Manchester United legend and U18 coach Darren Fletcher recently underwent knee surgery, but refused to step down from the line and continue to direct the team's game.

Fletcher led Manchester United's U18 wins in four games this season, and earlier this month he was injured while raising funds for two club foundations in Manchester United's legendary match against the Celtics, further demonstrating his professionalism.

This week, he underwent knee surgery for this, but refused to take leave and insisted on coaching on the sidelines every game. "He is a Scotch and has toughness in his bones."
