Number of things contributed to that result. First of all it was a much improved defensive performance from Villa. They fought hard today and deserve some credit for that.
Second it was a typical post CL away match hangover performance from us. Too many key players weren't at the races today.
But you have to ask questions of the manager. He got the subs all wrong. I can understand the first one but Sterling should have gone in the middle not de Bruyne. Why he thought bringing Delph on instead of Iheanacho was a good idea I'll never know. It added nothing to us but got the Villa fans fired up. A shocker of a decision in my view.
And after that time wasting and that terrible unsporting throw-in by Gestede, I hope the cheating bastards go down. Mind you, Joe Hart has to take plenty of blame for that incident as well and showed how brainless he is. He should (1) have played on unless told not to, (2) if he had to put the ball out then put it out well down field so they couldn't waste any more time and (3) just let the throw go out for a goal kick instead of trying to play it.
Still, with Arsenal dropping 2 points, we're still top going into the break.
