The 23-year-old has moved back to Real after spending two years with Almeria.
“I am delighted that they are going exercise it because my dream is to triumph in Madrid,” he told AS.
“I still do not know what will happen, but the fact they have decided to buy me back is testament to my work over the last two seasons that I feel has been good.
“Now I want to stay with Madrid.
“He [Florentino Perez] called me to tell me of the intention to exercise the buy-back clause. He told me to rest and that when I returned we would see what happens.
“My first option is to stay, but we will have to see how many forwards there are at Madrid. For a player like me, who comes from the youth team, it is difficult to win a place.
“What I need is to play games and I want to be able to do that with Madrid.”
“If I do have to go then Valencia would a great option. They are a big club and they have Unai Emery as coach, who I had a great relationship with at Almeria,” he continued.
“Whatever happens, if Madrid do not want me I will not see myself as a bargaining chip for them to use.
“Technically they may think that, but I would not see myself like that because I will go where I think is best for my career.
“It would hurt a bit. The club has spoken about having more Spanish players and for the time being they are showing me respect and that means a lot.
“But if they decide to sell me then I will not leave with any problems.”
“I have already said that I think that is a great club and it would be incredible to play alongside Torres. But I prefer not to talk about that, because for now I am a Madrid player,” he added on Liverpool.
