Stan Kroenke
Kroenke appeared on this list previously and also owns Arsenal F.C. in the English Premier League. However, he has a mixed relationship with fans because he made mistakes that damaged the club’s prospects. In 2006, he finished building a new stadium for the club. But this meant that they didn’t have the money to compete with their rivals.

It was 2022 before they became a genuine contender again. Also, Kroenke failed to plan for the departure of long-serving manager Arsene Wenger. This was a terrible miscalculation because nothing lasts forever. It had a shocking impact on their fortunes because of the transition (via The Mirror).
