Stan Kroenke can be held responsible for a lot of things that go wrong at Arsenal but if next season is a busted flush it will all be on Unai Emery.
That may well sound harsh but at the end of the day, he is the man that picks the team, does the tactics, implements strategy and demands who the clubs buy.
Now, that last part may not be so clear cut but put it this way, if he asks for a central defender and the club do not provide one then he should resign in protest because it is as clear as day that a new centre half is a necessity.
If he decides to stay in the event a new centre half is not bought then that is on him.
You do not need a degree in rocket science to know the weakness in the team and if Emery does not get that sorted and remains at the club then the buck stops with him and cannot be passed along.
Last seasons collapse was down to Emery, he had the team to get Arsenal into thrid and the Europa League final he cannot then put it on anyone else if that very same team folds like a pack of cards.
But it was his first season and so allowances are made but not for a second season and not when you have had ample time to sort out the deficiencies.
Some will, of course, argue that Kroenke employed Emery and so the buck should stop with him and that is a valid point but Kroenke can only do so much and when you employ a serial winner of the Europa League and trophies in France you cannot be blamed for expecting more than an end of season collapse.
