Or has football moved on? His teams press and pres hard, that's about it tactically with him. I think the game is moving beyond just pressing but tactically he isn't.....just a theory.
No, football hasn't moved on. All the best team press hard. His issue is that his team has slowly deteriorated and the style of football Liverpool want to play requires a high level of technical execution and application and they haven't got that anymore. Its a bit like a house of cards.
He has full backs who are pretty poor defenders so he needs to make sure they are mainly being used to attack. When the team isn't relentlessly winning the ball back up the pitch they have to defend. When they defend they are not good at it and they also aren't contributing to the attack as much.
Their midfield is ageing and has lost some of its energy and bite. Fabinho isn't the player he was, they miss Wjinaldum and Milner/Henderson aren't the force they once were and are becoming injury prone. They no longer dominate the midfield and again, teams are playing through them and not getting pinned back in their own half as much.
The forward line has lost Mane and replaced him with a pale imitation of the guy. Firmino has been in and out of the team for a while now but at his peak was brilliant for them. Diaz looks good but still not Mane and hes been injured. Jota is decent but again, injured a fair bit. Nunez is struggling to find the goal despite a lot of good work. So far Gakpo looks a bit lost.
Salah is off the boil and the lack of threat from Liverpool means that teams know that shutting down Salah will kill a lot of Liverpools threat. Previously Mane and a host of other players would score if you put too many resources on Salah. Thats no longer the case.
Its a mess of injuries, players getting older, players falling out of form and the general quality of replacements for outgoing players dropping.
Liverpool need to spend big next window but they have made the mistake of leaving it too late and they almost certainly won't have even Europa league at this rate. They probably need 2 CMs and a top class forward which they won't get because they have so many already.
