Yes many of them saw it as a loss and I agree seeing as I don't think they'll do much in second leg.
As for Wenger going and AFTV changing? No they'll still moan when results don't go their way under new manager.
They do but something tells me an Ancelotti or Benitez will be hired. I know Ancelotti never manages rivals of formers clubs, but the way he was treated by Chelsea, I think he would take the Arsenal job.
