it doesn't work mainly due to Casemiro, he keeps giving away the ball with his stupid passes in positions where you can't really afford to give away the ball then it looks like we are being carved apart when in reality it's just what happens when you make technical errora you shouldn't be making.

and then he failed to track his man multiple times who then scored from a cutback pass.

against Brighton he was finally taken off as punishment Bruno played as 6 and did the same thing, didn't track Pedro and he scored from a cut back.

these are errors that are simply on the players, no matter the tactics if you keep fucking up the basics.

Ole said the same thing, people get too int9 the tactics side of things but if you keep losing duels, put in less effort than the opposition then tactics doesn't matter, there is no tactics that can make that work.
