Manchester United FA Cup winner Paul McGrath says he's been won over by manager Erik ten Hag.

McGrath wrote for the Sunday World: "Erik ten Hag has only to look across the Old Trafford technical area today to absorb the most vital lesson in survival.

"David Moyes's presence in the away dugout offers a timely reminder of the gargantuan scale and responsibility that comes with the office of Manchester United manager.

"And, critically, of how the most essential imperative for any individual stepping onto Alex Ferguson's old throne is to somehow emerge from the Glaswegian's vast and imposing shadow.

"It is something Moyes could never do and the reason why he lasted just a few painful months in Manchester.

"I haven't agreed with all of Ten Hag's decisions.

"But his strength of personality has impressed me. He doesn't seem remotely intimidated by the alpha males that populate the world's biggest club.

"That he didn't hesitate in either dropping or disciplining Cristiano Ronaldo, when he felt that was the right thing to do, illustrated the courage of the Dutchman's convictions.

"It was a big test for a manager in his opening weeks in the job and he did not shirk."
