The Atletico Madrid chief says the 25-year-old's participation in the Champions League final depends on his experiment horse placenta treatment
The Spain international's goals fired Diego Simeone's side to the Liga title but he picked up a hamstring problem on the final day of the season at Barcelona.
In a bid to recover his fitness for Saturday's Champions League final with Real Madrid, the 25-year-old is undergoing horse placenta treatment but Cerezo does not want to harm him further.
"It depends on this horse placenta that he’s going to be treated with," he told AS.
"I don’t know, because I’m not a doctor. And, to be honest, if it’s harmful to him then it’s best if he doesn’t play. But, if he doesn’t play, whoever plays in his position will do phenomenally well.
"We’ll look to go out and win. Depending on the course the match takes, we’ll win or we’ll lose; but the team is mentally prepared, is strong and is up for it.
"That doesn’t mean we’re going to win, but at least we’ll bring something to the match. It’s 50-50."
The Madrid derby Champions League final kicks off at 20:45CET on Saturday in Lisbon.
