‘Finding out’ is separate from actually stopping it. Poch nailed the set up but they still needed an awful lot of things to go their way to get the result that they wanted.

Chelsea also didn’t play a 442, they played a 433. Their front three were compact creating a 6-man box with their midfield which was the goal to mitigate our central progression. It worked for sure but we allowed it to work by being abject in possession. If we were anywhere close to our usual level it would have been much more difficult. Also doesn’t help that both Martinelli and Saka weren’t their usual level which is what Poch probably banked on by leaving their fullbacks isolated all game.
