Great turn by Diallo and then just got overexcited, should have continued the run down the wing which would have then given him the option for the cutback.
Those cross field balls to the fullback that haven't really been coming off do support this, it's as if we expect them to be in more space than they are.
You do wonder if we planned our attacking moves around their fullbacks being higher up the pitch due to the three at the back, and them switching to a back 4 has messed with us.
