  Guardiola won his first 10 games in charge of City before suffering a first defeat at Tottenham before the international break.
  But Xavi - who left Barcelona in 2015 after winning his fourth Champions League title to play in Qatar - has seen enough from the club's early season form to suggest that Guardiola can make a big difference.
  "If you see the games of Manchester City you can see his style," Xavi said.
  "As a player he was a big reference for my career, and as a coach.
  "We made history with him in Barcelona. Barcelona always have the best coaches but Guardiola made a revolution; not only at Barcelona but across the world.
  "When you see him on the bench you can see his passion for football. I know him and I know he can do it."
