"We are proud to have the best players in the world, and proud to welcome back one of the best coaches in the world, a 'madridista' like José Mourinho," Pérez told the football club's website.
Benfica's price tag for José Mourinho, who was at Real Madrid from 2010 to 2013, is expected to be 15 million euros. Benfica has not yet confirmed that Mourinho is leaving the club.
Pérez, who has held the position since 2009, was re-elected last year, but after another season without a title, an extraordinary presidential election was held on Sunday. There, Pérez was challenged by Enrique Riquelme.
Pérez was also president of the La Liga club from 2000–2006.
