The 21-year-old Mexican striker passed a medical in Manchester this week and has agreed personal terms with United and will join the Premier League side from Chivas de Guadalajara in July.
United boss Sir Alex Ferguson said: “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.”
