Wait, aren't you one of the people who don't think Messi is on another planet to Cristiano Ronaldo? You think the two players are close in terms of their influence on the team. Yet, you give managers like Mourinho and Ancelotti who had Ronaldo in their team credit, but you don't give credit to those who had Messi in their team. You need to make your mind up, either Messi is so much better than Ronaldo that whoever manages a team with Messi in it has a clear advantage, or if they're close, then you can't give one manager credit and not the other.
But of course, your opinion will always change to suit the narrative you're trying to further.
