I can't help but go back and forth on Kroenke.
While it's no secret all his North American clubs are shit, and he doesn't care about winning, the people actually operating those clubs fire coaches all the time if it's warranted, because they do want to win. Jeff Fisher didn't even finish the Rams first season in LA because their fans sent a loud and clear message, and that was "if this shit continues, you'll be playing in a half empty stadium." Same with the Denver Nuggets and Colorado Avalanche of the NHL. Arsenal supporters will not do that.
There's another big difference: in all the three cases of the Rams, Avalanche and Nuggets, there's a General Manager who is higher up on the food chain than the head coach that usually fires the head coach. If the GM starts to slip, a president or CEO is usually there to pull the trigger on him. In Arsenal's case, who would dare put Wenger on a hot seat, let alone step up and sack him? He answers to no one because he has the board wrapped around his finger. If the board wanted a change, one would have happened already. Arsene calls the shots, and he has no one to hold him accountable.
