The Millo coach is gunning for his 10th title in just over four years at the club's helm - and sides in Europe are beginning to sit up and take notice
If pressed to name the most successful Argentine coach currently active, Diego Simeone or Mauricio Pochettino would top many football fans' lists. Both have achieved impressive success at relative outsiders, re-establishing Atletico Madrid and Tottenham, respectively, as challengers at the top of the table.
Jorge Sampaoli, too, might make the argument, despite his recent abortive attempt at taking Argentina to World Cup glory; Marcelo Bielsa too, for pure experience and enthusiasm, deserves to be in the discussion.
