Loris Karius (Liverpool):
The second shot stopper to make the list, Karius, was expected to be the man to carry Liverpool to the top of the table this season. But after less than 10 appearances, the German goal keeper was replaced by Simon Mignolet, the most error prone keeper in the league, in the first team. The 24-year old summer buy has been nervous right from his first game and cost Liverpool 5 points in games against Bournemouth and West Ham before Klopp changed his mind. He is still an option for the long term but having left Liverpool reeling with Mignolet, Karius makes this list as one of the biggest flops in the Premier League this year.
