Manchester United Treble winner Wes Brown was disappointed with the jeers aimed at Harry Maguire during Tuesday's preseason win against Crystal Palace on Tuesday.

Maguire had avoided a negative reaction in Bangkok and United's first friendly at the MCG, but the centre-back was jeered during the start of Tuesday's 3-1 victory against Patrick Vieira's Palace.

"Look, Harry Magiure has a bad season, he doesn't need me to tell him that," Brown told sundayworld.com at a Bookmakers.com event.

"What I would say is no supporter should boo a player if he is out of form. That's when he needs support and real fans should get behind a player who is trying his best.

"Maguire has been trying his best, but it just hasn't been happening for him. We've all been there, I know I have. The problem is, when you play for a big club like United, the spotlight is one you."
