Both sides are going into the match with full confidence in much as the Gunners have not been in their best performance yet this season but are yet to lose any match and sitting fourth in the English premier league and with a comprehensive win over PSV with their best-attacking display of the campaign I think they are the favorite, while spurs who sits second with 13 points from their opening five games after a dramatic win last time a trip to emirate stadium is their toughest of the season so far and will provide a good indicator of exactly where spurs are in their rebuild under the new manager.
