#10. Vincent Tan (Cardiff City)
After becoming the owner in 2010, the Malaysian businessman Vincent Tan initially made a series of generous decisions to satisfy the fan base of Cardiff City Football Club. But after the club gained promotion to the English Premier League, Tan’s decisions went erratic.
While Cardiff City is famously known as bluebirds, Tan decided out of nowhere to change their strip colors to red and black. Apart from it, Vincent Tan sacked Cardiff Boss in the midst of the campaign and replaced him with an inexperienced Ole Gunnar Solksjaer before replacing Cardiff’s head of recruitment with a 23-year-old Kazakh. As a result of all this distraction, Cardiff got relegated just one season after getting a promotion to the England’s top tier.
