Manchester United boss Ole Gunnar Solskjaer insists he was happy with Mason Greenwood's performance in their FA Cup defeat of Watford.

Greenwood started up front for United against Watford but struggled before he was substituted for Anthony Martial in the second-half.

The 19-year-old has only mustered three goals all season and United coaches see his role as more central, despite thriving from the right for most of last season.

"We had a front four with Dan [James], Juan [Mata], Jesse [Lingard], with Mason in front of him," Solskjaer explained. "With the licence to chop and change a little bit, find positions.

"Mason's a naturally floaty forward anyway, sometimes when you're young, staying through the middle is a challenge, and he tried to get a touch on the ball and got wide. I felt he benefited from this game, Mason."
