Real goes there with 4-2-3-1 and gets shat on every single time.
You have to play with a stopper infront of your 2 CBs to plug the hole Messi likes to play in. Look at their 1st goal. Messi comes off the CBs into wide open space, turns and starts sprinting at them. Then Real gets fucked, a couple guys jump in and it's over. You need a player there so Messi can never turn.
It was a fucking slow build up that turned into something resembling a counter-attack all because of the god damn "false 9". Just put a player there FFS.
