Fair enough . Wenger is not totally innocent for this defeat . But he made all his best players available . You could say he should have started Chamberlain but if Sanchez or Cazorla or Ozil were benched you could still have said the same .
And even though , in a big game you don't throw all your big guns on the pitch . You keep at least one who can change the game when the legs are tired .
The Flamini and wellbeck situations are red card cases without doubt but there are consequences of the referee inability to deal properly with similar previous situations . For me our players let us more down than Wenger . Of course , it is my own opinion . Regardless of the fact that many don't share it but that is my opinion .
