Darmian started life at Old Trafford brilliantly and endeared himself to fans with a string of fine performances. However, he has lost his place in the team as of late after some subpar displays.
Supporters had high hopes for Memphis, meanwhile, but the young Dutchman has so far struggled to make an impact at Old Trafford.
Irwin, who was part of United’s famous treble-winning side in 1999, backed the pair to bounce back.
“Darmian came in and started fantastically well and I think when you are getting used to the Premier League, you sometimes go off the boil,” Irwin said.
“As Memphis Depay has as well, you go off the boil a little bit. But they’ll come back strong.”
Both players are too talented to fade away into obscurity and Irwin is right in saying that they will return to form. There is still a long way to go over the course of the season and both Memphis and Darmian will have important roles to play.
