Tipped by Ferguson as an outsider for England's 2010 FIFA World Cup squad, the 21-year-old took slightly longer to make his mark than his manager thought.

However, when he reports for duty at United's Carrington training complex later this month, Welbeck faces an even more formidable challenge, living up to his manager's high expectations.
And for that he will need to increase his output from the 12 goals he scored last term, nine of which came in the Premier League.
"Danny can be a top player but obviously he will have to improve his goalscoring," said Ferguson.
"He got nine goals last season but if you are going to be a top striker you have to get 20 or above.

It is a good job too as it allowed more thorough treatment of injuries that otherwise might have halted his progress.
"He's always had growth spurts and all little things like weak knees and weak thighs. It was happening all the time," said Ferguson.
"So we fostered him from the age of nine right through that period when he was developing."
And, for defenders at any rate, the nightmare is that Ferguson does not feel Welbeck has completed that physical development yet.
"He's not got his full body yet," he said. "There's a lot of growth in him yet.

In fact, the only difficulty United is encountering with Welbeck just now is the frustrating amount of time it is taking to negotiate a new contract for the striker, whose present deal expires in 12 months' time.
It had been hoped negotiations would be concluded before the new campaign gets under way.

Once again at a major tournament, Rooney failed to do himself justice, missing England's opening two games through suspension, then producing below-par displays against
Not that Ferguson was entirely surprised.
Having worked with Rooney for eight years now, he always felt that lengthy gap between his star man scoring for United in its last day win over Sunderland and his opening salvos of
"I always thought it was difficult," said Ferguson.
"We know him better than anybody and he needs a lot of football.
"Wayne's a stocky lad. If he misses a couple of games, it takes him three or four to come back and he didn't play from his last game (for United) on

However, when England needed a big performance from its talisman against
"He didn't look as sharp as normal," said Ferguson.
"It is very hard to play two big games in four days."
Ferguson sees no long-term problem though.
Neither does he feel Rooney was placed under too much pressure in an era when star men are scrutinised like never before.
"It's a fact of life," he said.
