#2 Simon Mignolet
An obvious choice for this list, Simon Mignolet failed to even appear in one single Premier League game last season. I get that he serves as the back-up keeper to Alisson, but there are much cheaper options out there who would demand far less in wages per week. Mignolet, like Lallana, is robbing a living at Anfield right now.
Really, his role should be taken up with a hot young prospect who could learn a lot by watching from the bench. Mignolet is 31 years old now and rapidly heading towards his final years in the sport; a youngster in his seat would be more valuable and also show fans that the club is looking towards the future as well.
And surely Mignolet would be after a first-team spot anyway, and not be simply content with a position on the bench for every single match. Where's the ambition there?
