What are you question marking??...so the players who had the best chance to prevent the goal did nothing wrong..got it...a CB should take over the runner from the midfield...that`s his job when he doesn`t have a player to mark & a GK should be able to make 2/3 steps forwards to catch a cross which was at least 4 sec. in the air
I've just told you the goal stemmed from gvardiols piss weak defending so he was clearly at fault. Gundogan didn't give any one a shout about the runner which was his man from midfield so how is stones supposed to know he's there?
The goal wouldn't have happened in the first place if gvardiol had challenged for the ball or at least tried stopping the cross.
Cant blame it on stones and ederson for having split second chances to stop it when the other two just gave up their jobs.
