9) Chris Sutton (British)

Chris Sutton is one half of the famous SOS – Sutton and Shearer – strike force which helped to win the league for Blackburn. This former Blackburn Rovers and Chelsea striker was the first £5 million transfer football player in the United Kingdom. Sutton’s finances hit a low in 2014. This was because he became embroiled in a multi-million pound fraud after investing £50,000 in a spread betting foreign currency scheme. He and his wife invested £100,000 into the scam run by accountant Simon Grinter’s company. He went into bankruptcy in May 2014.
