He's been a blind spot now for how many managers?
5?
Rafa, Hodgeson, Kenny, Rodgers, Klopp.
Lucas is by no means a great player but if every other player had his attitude and application we'd be in a much better place.
As you've correctly stated we crumble not because of Lucas but because we are set up to fail unless everyone of our front 6 play well and press well.
When they don't we go to shit, Lucas included but he's an easy target.
Matip was supposed to be the signing of the year 'the best since Hyppia', where the fuck was he?
Clyne, Milner, Lallana, Coutinho, Firminio? They were all utter shite, yet people still fixate on the player who actually you can understand getting roasted as he's slow a short fuck and was pitted against an opponent with lightening pace, with no defensive cover in front of behind and no pressure on the through ball.
A lot of issues are on Klopp and his approach including exlosing our CBs if you choose to pick that pair
