Actually, anyone with a brain knows it was only managing one win out of our last 12 games that took us down. Wellens certainly wasn't exempt of blame with some of his team choices, but then again had Al not decided to take things into his own hands during the run-in and start openly criticize teammates to players he'd called into his office, or call meetings to humiliate others players in front of the whole team (particularly before the final game of the season), or even picking which players got paid on time above others, then perhaps we would have found that extra win.
But then again I suppose that doesn't fall in line with your MO (no pun intended) does it..
