Yes of course Kos should be a focus, that's obvious. But just after the moment of impact what is the rest of the defence doing? This is a freeze frame of our shitty zonal system in action. Merts is marking empty space. Monreal is a yard behind the play, also isolated. The spuds have two men attacking the ball, overloading our one man in the zone. Spuds are on the front foot, look at us.
