The Mexico international is over the moon with his transfer to the Champions League holders and can't wait to get started
The Mexico international has failed to nail down a regular spot in the United first-team since joining in summer 2010 and signed for Carlo Ancelotti's side on a one-year loan deal on Monday after passing his medical.
Hernandez says he is keen to get started and prove his worth at his new club and insists he doesn't feel pressure in following in the footsteps of compatriot Hugo Sanchez, who won five league titles in the seven years he spent at the club.
"I am delighted to be here and grateful to Real Madrid for giving me this chance. I will do everything I can to help the team. Playing for Real Madrid is a dream come true. Everybody in the world knows Real Madrid," Hernandez said at a press conference.
"Hugo Sanchez had a great career here, but I want to do my own thing and make a name for myself. I will give my all to repay Madrid for the confidence shown in me. I want to win titles with Madrid.
"A big team cannot rely on one player. You need a team to be successful. And out of all the big clubs in the world, Real Madrid are the biggest."
The 26-year-old could make his official Madrid debut in the Liga match against at home against Atletico after the international break on September 13.
