TBH, the player I was fearing the most before this match was Bruma because of the pace and counters. But then I see a 3-4-1-2 with 3 rather slow players up front and I'm thinking maybe they want to try and pin us back since there's no such thing as a defensive 3-4-1-2 really. You'd have to make it a 3-5-2 and drop the trequartista for a true DM.
You can't defend the middle of your backline with just 2 CMs because one will constantly be pulled out of position.
I give up. It's Mancini after all. $#@!er is clueless, I have no idea what he's doing.
