The Mexico international linked up with Carlo Ancelotti’s side on transfer deadline day for a season-long loan, and is hoping he can do enough to earn a permanent deal at the end of the season.
Hernandez, who joined the Red Devils from Guadalajara in 2010, decided to leave Old Trafford after the club moved for Monaco’s Radamel Falcao, with Danny Welbeck also quitting for Premier League rivals Arsenal.
The 26-year-old has already looked impressive after making his La Liga and Champions League bow, and talking to Claro Sports, the hitman admitted that United’s lack of belief failed to inspire him with confidence during his three-year stay.
He said: “There was no confidence. I remained patient and that’s why I’m here today. It was a very tough year especially because they didn’t believe in me.
“I had the chance to meet Ancelotti when he was Chelsea coach. The faith he has in his players motivates me and makes me work hard.
“I really want to make the most of my time here. Any footballer dreams about joining Real Madrid. I know I’m here for a reason. The statistics support me, I’m a good player and a good person.”
