The conditions are totally different. The reason is simple, against the 2011 Barca no team dared to commit men forward and play a high line, or they'd lose. Espanyol tried that to a point and lost 5-1 at their home ground. If current Bayern tried that, we would've beaten them easily.
Because of this reason, we could get away with situations like Messi staying in offside more than the other players. We still had superiority, because teams would dare press us. We were an un-press-able team back then so to speak.
This is not 2011 anymore, and we don't have the greatest midfield of all time.
Of course I know that and that is the answer I expected, so here comes my point:
Is Messi
so different from back then (age adjusted answer please)
or
is all of the other players and the managers
so shit compared to then.
Messi has played the same game since 2010. He has reinvented himself a couple of times. He has lost some abilities and gained some others.
But he was never, in no way shape or form a pressing or "make runs behind the defence all game long" machine. He pressed when he felt there was a chance, and made runs when he caught the defence sleeping and a good ball was about to come.
He knows how to play in a free position system. Drifting left, center, right or anywhere, depending on the game situation. As every other player in that team. There was just no fixed position per se.
And you constantly accuse him of four things.
1. He does not press - Which he never did.
2. He does not make runs behind the defence - Which he mostly did in his teens and since then a couple of times per game (with passers like Xavi and Iniesta providing).
3. He does not stick to his position and drops deep - Which is what all his game has been about since 2010.
4. He is to blame for the board keeping the other seniors and EV - Which is simply at best case scenario - unknown. And even if all that is true, that is not his responsibility, but the boards.
So you basically (except 4) don't just call out Messi a bad player overall now, but since 2010. That's my point.
