Pep Guardiola

Pep Guardiola holds the record for most trophies won by any manager in elite European history—40 titles in just 16 seasons, which is 27% more than the average tally of managers ranked #3 and below here. At Barcelona, Bayern Munich, and Manchester City, he won 11 league championships and 3 Champions Leagues, including a historic Treble in his debut season (2008–09) and another in 2023. His 2008–09 Barcelona team is widely considered the best club side ever, and he led City to four consecutive Premier League titles (2021–24)—a feat faster than the average rebuild by rivals. His positional play philosophy has revolutionized tactics worldwide, directly influencing managers like Mikel Arteta and Xavi.
