that level, you get exposed quickly in the first-team group but his performances are believed to have impressed Sir Alex and the rest of the players.
Which former United player is he most like?
Although he is not as big physically yet, there is a little bit of Gabriel Heinze's style about him in terms of his approach to the game. If he does as well as the Argentinian, everybody will be delighted.
Will he be able to settle in a new country?
There is already a group of young Spanish-speakers at Old Trafford – the likes of David De Gea, Javier Hernandez and Angelo Henriquez – who can help him with the language and adapting to life in Manchester. Hernandez was a big help on the training pitch during his trial period, passing on the coaching instructions.
So, what's next?
The Under-20 World Cup in Turkey (21 June to 13 July). It will be another challenge for him and United have a good presence at the tournament (Henriquez with Chile; Tom Thorpe, Sam Johnstone and Larnell Cole with England). Brazil and Argentina did not qualify, which was a surprise, but it gives other teams and players a chance to impress and the Reds will be keeping a close eye on events.
