The chance to play in this historic stadium and to work with Jose Mourinho was something I could not turn down.

I am very proud to be the first Chilean player ever to play for United's first team and I hope I can show our fans all around the world why the club wanted to bring me here, he added.

Alexis is one of the best attacking players in the world and he will complete our very young and talented group of attacking players, Mourinho said.

He will bring his ambition, drive and personality, qualities that make a Manchester United player and a player that makes the team stronger and the supporters proud of their club dimension and prestige."
