Arsenal will no doubt look back at a remarkable passage of play in the second half with regret which saw their match against Manchester City dramatically turn on its head.
The Gunners had impressed in the first half and led the champions 1-0 at half-time following Bukayo Saka's strike, having also been denied a penalty after Ederson's challenge on Martin Odegaard.
But City were given the chance to equalise from the spot ten minutes into the second half after intervention from VAR, when referee Stuart Attwell decided to overturn his original decision following Granit Xhaka's tackle on Bernardo Silva.
