Sane had just as much time and space versus Bruno. They are world class players to overly criticise our defence is stupid.
Edit to add do you think any of our players would have scored from either of those chances, Knockaerts chance was easier than both.
Similar situation to the other goal too, nobody on that wing picked up Sane (Knocky or Bruno one of them should have) which resulted in the uncontested cross and shot by Silva. Only difference was Bong wasnt berating his team mates and it was in open play not a set piece.
