Toni Terry
For all the soccer or football fans out there, this is one of the most infamous cheating scandals in sports history. John Terry had a legendary career as a key member playing for Chelsea, a team based in London. He was the captain of his team for some time and an invaluable member of the club.
He really should have known that he needed to set a better example for everyone else. But when he cheated on his wife with his teammate’s ex-girlfriend, it really was a blow not only to his marriage but to the club. She forgave him, but fans still sing about this incident every time he plays.
