Sportsmail studies 55 players in question and looks at where they are now

He has given notepad of names he handed consistent first-team football to

The United boss claims he has given 55 players their chance as youngsters

Jose Mourinho was unveiled as Manchester United's manager on Tuesday

Jose Mourinho came out fighting over his perceived aversion to offering youth a chance armed with a notepad of names he has handed consistent first-team football to during his managerial career.

The new Manchester United manager foresaw questions on his strategy, pertinent given the amount of teenagers who made their debut under Louis van Gaal last season.

Those included Marcus Rashford, who is set to play a significant role under Mourinho and alongside Zlatan Ibrahimovic.

Mourinho - whose list of players surprisingly included Arjen Robben at Chelsea - was keen to reject what he believes is a myth about his management.

'You know how many young players I promote to the first team from academies? Forty-nine,' he said.

'Do you want to know who they are? Forty-nine. Forty-nine. If anyone is interested, I can give you that.

'I promote 49 players from the academies from the clubs and with two factors, that are very important on these records, because sometimes you promote players because you don't have another chance, because you have so many injuries that you don't have another choice.

'You have to bring through players from the academy because you have so many injured. That is one factor and the second factor is when you are not playing for big targets, it is easier to bring them up outside the pressure of the big moments.'

Mourinho offered his notebook out at the end of his press conference at Old Trafford but quickly saw that ruined after a glass of water was accidentally knocked over.

Mourinho's appointment will raise fears that Manchester United's academy players won't get their chance

The United boss then privately recounted the names and the list was later sent out with more than previously suggested, finishing with 55. On it are either academy products or players under the age of 21 he has given debuts to at their new clubs.

Robben cost Chelsea £12million in the summer of 2004 having starred for Groningen and PSV as well as at Euro 2004.

The Dutchman had made his international debut 18 months before making his Chelsea bow and was being chased by the world's top teams - including United.

Mario Balotelli is also on the list having already made his debut for Inter Milan by the time Mourinho took over in 2008, although he did flourish under the Portuguese, playing 70 games in two seasons.

Mourinho also pointed to a number of youngsters at Real Madrid, including Raphael Varane, Casemiro, Alvaro Morata and Jese.

'Some of them are big names, they are today Champions League winners or in the Euros, playing for national teams and it is a lot,' Mourinho added.

'So once more, one lie repeated many times, sometimes it looks like it's true but it will be always a lie. So for many times, many of you – with or without intention – that is not the point, I don't care about it – but it was not true.

'My record of injuries is very very low. Even in many years from the Champions League studies about every team, my teams were many times the teams with less injuries in the whole of Europe.

'So I never promote players because of need, I did it because of conviction and decision. And last year was the only season of my career when I was not fighting for the title.'

Here, Sportsmail looks at the 55 players in question and gives the lowdown on where they are now.
