Martin Odegaard hits Arsenal winner to sink Napoli 

Arsenal won all eight group phase games on their way to last season's final, and they are up and running after a fine win in Italy.

Arsenal registered 26 attempts - their highest total in a single match in the Champions League since the start of last season.

The Gunners were guilty of wasteful finishing and were heading for a frustrating draw in their first game in the Champions League since losing last season's final in agonising fashion.
