Manchester United legend Denis Irwin says it's time for their young defenders to come out of their shells.
Irwin sees Jonny Evans as the only loud voice amongst United's current defence.
He wrote for the manutd.com website: "I do think some of the defenders need to work on the vocal side of their game. Jonny is vocally strong but a couple of the other lads are a little bit quieter. One of them will have to take control and move people around.
"I'm sure that will come and I'm sure the manager will have encouraged them to be vocal. Any new system needs that but it comes with experience, too. When you're younger, you keep your head down a bit and get on with your game. It's up to the experienced players in defence to organise and Jonny's fine doing that."
