Pep Guardiola's decade at Manchester City has ended with ESPN ranking all 18 of his managerial seasons across Barcelona, Bayern Munich, and City. His departure follows 21 trophies in 10 seasons, though City's final title hopes faded when they drew with Bournemouth, allowing Arsenal to clinch the Premier League.

ESPN's ranking places Guardiola's 2010-11 Barcelona season at the top, with a remarkable 2.53 points per game average and Champions League triumph. His debut 2008-09 Barca campaign that delivered a treble ranks second, while the 2022-23 City treble season featuring Erling Haaland sits third despite a midseason wobble.

Guardiola's Bayern Munich tenure (2013-14) showed his tactical evolution with a 2.65 PPG but ended with Champions League semifinal heartbreak. His legacy remains untouchable despite City's financial misconduct charges, with Sir Alex Ferguson once calling his Barcelona team "the best I've faced."
