United last month agreed a fee with Mexican side Guadalajara for the 22-year-old before the player also completed a medical and agreed personal terms.

United had only been awaiting confirmation of his work permit to complete his transfer, which will go through on 1st July.


A statement on the club's official website confirmed: "Manchester United is pleased to announce that Javier 'Chicharito' Hernandez has been granted a work permit and will join the club on 1 July 2010."

Hernandez's confirmation as a United player had been held up because he had played less than 75 per cent of Mexico's internationals during the past two years.

He is, however, set to be a part of the Mexico squad at the World Cup finals in South Africa following which he is due to join United's squad for the Philadelphia leg of their pre-season tour of the United States and Canada.

Hernandez, who is nicknamed 'Chicharito', described his move to Old Trafford as "living the dream" after he completed his medical in Manchester last month.

United fans got a quick glimpse of his talents when he made a substitute appearance for Mexico against England in their 3-1 defeat at Wembley on Monday, before he scored in a 2-1 friendly loss against Holland 0n Wednesday.

Hernandez's signing is the first time that United have done a deal for a Mexican player.

When the deal was initially struck, United manager Sir Alex Ferguson described Hernandez as "an exciting young striker".

"He has been in prolific form for both his club and his country," Ferguson added at the time. "He will be a great addition to our squad."
