Its a mystery what was going on out there. I never heard Pep saying it but the commentator mentioned in interview how City had to be conscious of the long ball.
What happened to Cancelo happened to Dias earlier in the match. When you are last man you dont try and get round the player but keep goal side and hold him up.
We tried this on a few occasions basically turning the duel into a 50/50. That is not on Pep those defenders should either have doubled up or defended differently, but instead, and it happened througout the match, they were going to ground, diving in or trying to steal the ball rather than play percentages.
Latter stages of the Champs lge this will be exposed again like it is every year. Defensively the dominance of the side masks the deficiencies at the back but bites us whenever we face a top side.
