Who has the best managerial achievement?
Sir Alex Ferguson without a doubt.
Sir Alex stands out as the manager with the best overall achievements in football history, primarily due to his record of 48 trophies won during his managerial career. His most notable tenure was at Manchester United, where he secured 37 titles, including 13 Premier League championships and two UEFA Champions League trophies. Ferguson’s influence and success over 27 years set a benchmark in football management that remains unmatched.
Xabi Alonso has just got started and still early in his managerial journey to be considered on the same footing as the above legends.
As a manager, Alonso has quickly gained recognition for his success with Bayer Leverkusen. In his first full season, he led the team to its first-ever Bundesliga title, achieving an impressive unbeaten record throughout the season. His tactical flexibility and ability to connect with players have been highlighted as key strengths in his coaching style, drawing praise from notable figures in football, including José Mourinho.
I think his future in coaching looks promising, anticipating further success as he continues to develop his managerial career.
