Zaragoza were expecting to lose the Argentine with Madrid president Ramon Calderon willing to pay his £17 million buyout clause.
Indeed, some teammates were already resigned to losing the striker.
Pablo Aimar said: "Hopefully he remains. Whatever happens, I hope that it is the best thing for him."
Former Real Madrid midfielder Juanfran added: "Madrid always does the same when it is in a moment of crisis. I am sure that he isn't going to go, because he does not want to and because the club is not going to accept anything other than his buyout clause."
