The on-loan Real Madrid ace was speaking after winning yesterday's FA Cup final.
He told Marca: "I have great affection for Betis, all those who work for the club, who know the love I have for them and have been in contact with me all season. Betis means a lot to me.
"I am one of those who say that when you are happy, you develop your game. Right now I am happy, but it is time to rest at home with my family, with my girlfriend, who I haven't seen in a while, I've been alone in London for five or six months, so now it's time to be with them and reflect on the upcoming season."
