#2 Dejan Lovren

In April 2017, when Dejan Lovren was given a new 5-year deal to stay at Anfield, the football community online had a romp to laugh at, and why not? Lovren had been the scapegoat of many a Liverpool falling and was a symbol of shambolic defending errors at Anfield, and instead of being demoted to the bench and signing a new centre-half, Lovren's place at the centre of Liverpool's defence was cemented with a new 5-year deal.
The ridicule of the footballing community has been proven to be with sufficient reason too, as Lovren continued his woeful form this season, letting the wonderful attacking trident of Liverpool down on numerous occasions.
The fact that Dejan Lovren receives higher wages than Toby Alderweireld, arguably the league's best defender, represents the pathetic state of transfer activity at Liverpool and their inability to lock down targets such as Virgil van Dijk, leading to them killing their own title chances before it was born.
A decent defender on his best day, Lovren was a good strongman at Southampton, but he never had the stature to play for a big club. The money that was spent on him by Liverpool, making him Liverpool's most expensive defensive buy, always looked like a panic buy more than anything else, with his performances in a red shirt proving all the critics who deemed this move unwise, right.
Klopp should be aware of Lovren's defensive shortcomings by now and ideally should be looking for a replacement in the market before Liverpool's league and cup campaigns get tougher and more worrying.
