Man United manager had no tactical prowess so I left for Chelsea – he was very upset with me

Former Manchester United goalkeeper Mark Bosnich previously claimed Sir Alex Ferguson possessed negligible tactical prowess before making his move to Chelsea in 2001. Bosnich acknowledged Ferguson's exceptional talent-spotting and motivational abilities but compared him to an average jockey riding a champion horse. Ferguson was reportedly very upset by Bosnich's choices during his departures from Old Trafford.

Bosnich joined Chelsea on a free transfer in the 2000/01 season after falling down the United pecking order behind Fabien Barthez. Ferguson later criticized Bosnich as a terrible professional in his autobiography, citing significant fitness and dietary issues. Bosnich defended his record by highlighting his role in United's Premier League title win.
