He's a level above everyone to me, either still playing, who played at the same time, or who came before.
No-one has ever been able to score, assist, pass, dribble, read the game, play in multiple positions to the level that Messi can. It's indisputable for me. Like, if you even start trying to say that anyone's better I'm switching off from the argument. It's clear as day to my eyes.
