I've started paying a lot of attention to what we do from corners, and there is no common denominator. The players all take up positions and then that's the end of that. There's no organisation or plan to it beyond that.
Today for example, you can say "why is WIlliams picking up Van Dijk" but the fact is, no one is picking up Van Dijk, just like no one is picking up anyone else. Williams just happens to be the one stood near him so tries to do something.
Zonal marking is fine if it's done properly. We don't mark zones or players. We stand in places and hope that we get in the way. As soon as someone makes a run, or the ball isn't crossed directly to one of our players, or someone blocks one of our players from jumping, there is a problem every time because we react as no team in the history of football has ever tried these things until that moment.
Honestly I'm not in the Ole out campe, but if Ole was sacked purely on the back of this at this point he would have literally no argument. We are a professional football team and this is blatantly unprofessional. It's a literal example of incompetence...failing to do your jobs time after time not because you aren't good enough, but because you haven't bothered to learn how to do it.
