Speaking with Onda Cero, Perez revealed his admiration for both Liverpool manager Jurgen Klopp and Spurs boss Mauricio Pochettino and said he might consider attempting to lure the Reds manager to Santiago Bernabeu in the future.
"Klopp and Pochettino are phenomenal," he said.
"I've never tried to sign them, but that doesn't mean we won't try to in the future."
Perez also says he took little joy in seeing his team's great rivals Barcelona humbled at Anfield by Klopp's Reds.
"I was not happy about the defeat of Barca against Liverpool but it shows the value of what we have done these years in the Champions League," he said.
"I feel sad as the players have been whistled and as you, as journalists, have insulted them. It's not normal, we feed something that's not right.
