The 25-year-old joined QPR from Real Madrid on a four-year contract in the summer.
"I have wanted to play in England since I was a child," the Spaniard told The Telegraph. "Football was born here and they feel this sport in a way that they don't feel anywhere else.
"Not in Spain. In Spain football is great, they have good players but the sport is not the same as here in England. I would talk to my family and say 'one day I will play in England.
"I don't know when - maybe when I am 20, maybe 25, maybe 30. Maybe for the best team in England, maybe for a team in the second division. I don't know but someday I will play there'. And, this summer, I felt it was the right time to come here and test myself. I was plenty sure of that."
QPR will host Everton at Loftus Road in the Premier League on Sunday.
