29. Michael Owen
Owen was one of the top young strikers in Europe during his time with Liverpool. He famously scored a mesmerizing goal against Argentina when he was 18. Then he moved to Real Madrid but it didn’t work out (via Sky Sports).

Liverpool adores its sporting heroes and fans hoped that he would return. But there was outrage when he joined their fierce rivals, Manchester United. This cost him his relationship with the club because fans no longer respected him.
