I’ve said a few times this season that I like 3-5-2 and have the players to fit that system. However, like you I don’t think now is the time to start playing it. Maybe he’s a tactical genius that has suddenly found the formula, but I can’t believe for one minute he’ll play this way in the play offs which makes the whole thing pointless.
I hope it’s not an ego thing, I know he thinks he’s Pep lite, & Pep sometimes makes weird selections, but if we do start with a back 3 it seems a bit baffling.
