Manchester United announced Thursday a deal to sign Mexican striker Javier Hernandez from Chivas de Guadalajara for an undisclosed fee, subject to receiving the requisite U.K. work permit.

Hernandez, 21, has already agreed personal terms and passed a medical. He is expected to join United in July after the World Cup, should a permit be granted.

As part of the deal, United will play a friendly at the Chivas Stadium ahead of the 2010-11 season.

United manager Sir Alex Ferguson told the club's official Web site: "I am delighted to reach agreement with Chivas to bring such an exciting young striker, who has been in such prolific form for both his club and his country.

"He will be a great addition to our squad and we look forward to welcoming our first Mexican player in the summer. We are equally excited to play our first game in Mexico, opening the magnificent new Chivas Stadium in July."

Hernandez, or "Chicarito", as he is known, has scored 26 league goals in 63 games for Guadalajara and four goals in his first four games for Mexico's national team.
