Honestly, Bolton was not going to beat Arsenal today. It was a solid performance for the first 60 minutes or so, and yes, the sending off of Gary Cahill was unjustified, and yes, it changed the whole match. But really, Arsenal were eventually going to finish one of their 653 chances.
So put the noose away Bolton supporters, Stuart Atwell did not cost us this match. The boys from north London are just a better team than us. No surprise really. I suppose you could say that a free kick on the edge of the box rather than a Cahill red card would have led to us tying things up at two and then charging on to victory, but I think you would be wrong.
