VVD has had 2 seasons of brilliance at the CB position and it's telling IMO that all the laughing we had at Lovren's expense stopped, the season they won the CL and gave City a run.
To answer the question, a great system is not independent of the players, you can't have a great system with mediocre players. Klopp's system works because he has quality players at crucial positions in the team. That includes VVD. I'm even willing to acknowledge the quality of the likes of Henderson and Wijnaldum. It's not easy to do what they do.
Plus I think any conclusions made based on this weird system will be flawed. The players aren't playing in optimal conditions by their standards.
Precisely this. No player in the history of the game is an island, completely independent of the system he plays in, the coach he plays for, the teammates he plays with. When assessing how good or bad a player he is you have to take all the other factors into play.
So VVD by any definition is one of the best centre backs of his generation. The fact that he has both elevated and been elevated by playing alongside world class players for one of the best coaches of his generation in a system which seems to be the current dominant system of its time is just something that goes hand in hand.
So Zlatan bombed at Barca, Henry bombed at juve, Maradona bombed at Barca, Messi bombs for Argentina - it would be silly to assess these players according to these periods in their careers.
I’m sure Maradona would have had a golden period at Barca if he hadn’t been playing for Lattek in a thug team (the Barca of the early 80s were one of the dirtiest, most violent teams of the last 100 years), Messi might have won a World Cup with Argentina settling the Messi vs Maradona debate if he‘d had world class players like Valdano and Burruchaga to take the load off him, etc etc.
It’s basically impossible to separate VVD from the coach and system and players he plays for/in/with, any more than you can have a debate about how great a player Cruyff was without discussing Neeskens and Krol and Michels and that whole Ajax total football tactical setup, all factors which were enormously responsible for turning him into the player he became.
