Los Rojiblancos' president says that the Chelsea-bound striker's participation in the Champions League final depends on his experimental horse placenta treatment
The Spain international's goals fired Diego Simeone's side to the Primera Division 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."
