The Argentine manager played alongside both superstars, and he puts the former Fulham midfielder in the same bracket
Tottenham manager Mauricio Pochettino believes Mousa Dembele to be "a genius of football" like Diego Maradona and Ronaldinho.
Dembele has received rave reviews in recent weeks as Spurs emerged unbeaten from a run of fixtures that included clashes with Manchester United, Liverpool, Arsenal and Juventus.
The former Fulham man has been key to this fine form and his manager was in no mood to play down the midfielder's talents ahead of Tottenham's next Premier League match against Crystal Palace.
