Pep Guardiola (Barcelona)
Experience: Won just about everything as a player - except the Champions League - and in just three years as coach has developed Barcelona into a team proclaimed by many as the best of all time.
Honours: One Champions League (2009), three consecutive La Liga titles (2009, 2010, 2011), Copa Del Rey (2009), UEFA Super Cup (2009), FIFA Club World Cup (2009).
Tactics: Has developed the passing game into a virtual art form. But under him Barca are not just about passing, his team is also a byword for hard work - when they lose possession they press their opponents relentlessly,
Style: Bold and strong-minded - as was shown by his immediate announcement that superstar players Ronaldinho, Deco and Samuel Eto'o were surplus to requirements when he took over as coach in 2009.
Sir Alex Ferguson (Manchester United)
Experience: After a solid but uninspiring playing career, he established himself as a brilliant manager in Scotland before moving to Old Trafford.
Honours: He has won 47 trophies as a manager - he is the most successful in British football history, including three Champions Leagues and 12 Premier Leagues.
Tactics: His teams are characterised by skill and speed, especially hitting teams on the break. Ferguson's team have a blend of aggression and style - they are never bullied off the park.
Style: A fearsome figure from the start of his managerial career, Ferguson rules with an iron fist and is a master of the art of mind-games.
