El Confidencial says Perez was left so disgusted by the attitude of Real's players he is now weighing up quitting the club after the Champions League final.
The Real supremo feels betrayed by the players, which were so close to a historic Treble only to collapse so dismally in Vigo.
Perez is keeping his own counsel and apart from exchanging tense words with coach Carlo Ancelotti has not made his feelings known to the players with the Champions League final still to play.
But the president and his closest directors have already identified those who've let down the club and won't forget come the summer.
