If you lot want to believe in managerial mystical powers, by all means go ahead.
But you're going to have to re evaluate Benitez if you do. If he's so spectacularly good yet he's doing worse than Di Matteo - and butchered his last job at Inter, after turning us into a midtable team, it doesn't make much sense does it?
Where are those powers now?
Tbh, I'd say a bullet dodged in terms of rehiring him last summer.
Why? Your fish pasta?
What the stats show here is that when you give two managers the same squad the outcome is going to be largely the same even though the style might differ.
That is, the game is all about the players - the managers aren't important.
