Arsenal endured a frustrating evening as they were held to a draw by a dogged and determined Bolton.
Even some second-half brilliance from Robin van Persie failed to break the deadlock, with the Dutchman's exquisite lob hitting the bar.

Bolton did a good job of stifling Arsenal's spark in the second half, and had a good chance of their own whe
