3. Andy Carroll, Newcastle to Liverpool, Jan 2011 £36m With money to burn from Torres' sale to Chelsea, Liverpool splashed out a laughable £36m on a player who had only made his full England debut two months previously. Not surprisingly Carroll was injured when he arrived and didn't play his first match since March 17. Carroll scored six goals in 44 appearances for Liverpool before he was initially shipped out on loan to West Ham in the summer of 2012. Carroll's move to West Ham was finally sealed in June 2013 for a fee of £15m, but another lengthy spell on the sidelines hardly endeared himself to Hammers fans and he didn't score his first Premier League goal until March. More recently things have picked up for the big-striker, hitting his 50th league goal of his career before Christmas. Picture: ACTION IMAGES
