Wayne Rooney feels Danny Welbeck has the temperament to cope with the big occasion and would relish the opportunity to play at Wembley in Sunday's Carling Cup final.
With Dimitar Berbatov unlikely to feature having not been involved at all in this season's campaign, Rooney, Welbeck and Carlos Tevez are all vying for a spot in the side to face Tottenham Hotspur.
While Rooney hopes he'll be handed one of the attacking berths, he says Welbeck would not let anyone down should he be given the nod.
"I’m sure he can do the business," Rooney told ManUtd.com. "He’s a nice lad and when he’s come into the team he’s done really well.
"I think what’s surprised a lot of people is that he’s not been fazed by anything, despite being so young. He’s had the composure to take everything in his stride and play the sort of football we all know he can play.
"That’s great for the team and I’m sure if he plays on Sunday he’ll have no problems playing at Wembley and won’t let anybody down. I think when you're that age you don’t care about too much – you just want to get out and play football."
Sir Alex has promised to stick with the players who have got the Reds to this stage and Rooney remains hopeful of being involved from the start.
"We've all just got to wait and see what the manager says about Sunday," he admits. "It is down to him who plays."
