"If Manchester United could appear at the El Madrigal it would be a fantastic experience for me. I respect all teams, but Manchester United is a very, very big club," said the South American, whose last game for the Reds was as a sub against Chelsea on the opening day of the season just ended.
"I know that I am going to go back to England one day... and I would like it to be to United.
"I have to admit that I'm surprised that my first season in Spain went so well. I never expected to score so many goals so soon.
"Being in a small town is great for me, and I love the fact that I've helped Villarreal make history by reaching the Champions League.
"Becoming top scorer in Europe would have been worth nothing to me if we'd failed to gain a place in the Champions League. That is the thing I feel happiest about right now."

"I'm not trying to make excuses, but the language barrier was definitely part of the problem for me. But there was also the fact that everything happened so quickly.
"As soon as I arrived at United, all the fans seemed to expect me to score two goals a game. There was a lot of pressure and it got to me. There were lots of players with monster reputations at the club, and I was the last one in the queue.
"I didn't get enough time on the pitch to prove my quality. That was very tough for me.
"At Villarreal nobody rushed me. The coach, Manuel Pellegrini, was very calm and he wasn't in a hurry for me to score, simply because the supporters weren't in a hurry.
"Obviously I have been given more time on the pitch at Villarreal, but also, I have not put myself under so much pressure here. And I think that is part of the reason why I have scored so many goals."
