#1 Simon Mignolet
Simon Mignolet joined Liverpool from Sunderland for £9 million in the summer transfer window of 2013. He played 203 games for the Reds thus far and helped the club keep 66 clean sheets.
However, he never looked convincing in the goal for the Reds and made 13 errors leading to goals since joining Liverpool. The Reds signed Loris Karius to replace to the Belgian in 2017 but he also failed to make an impact at the club.
Nevertheless, Liverpool finally found their perfect goalkeeper, Alisson Becker, and the Brazillian significantly improved the Reds' defence since his arrival.
Simon Mignolet is currently a backup goalkeeper at Liverpool and is yet to make a Premier League feature this season. He was linked with a move away from the club last summer and Liverpool could finally get rid of the goalkeeper during the winter transfer window.
