SUMMARY
Arsenal held off a spirited second-half fightback from Watford to claim their first victory of the new Premier League season.
In truth, the points were won during a devastating opening 45-minute spell when the Gunners took complete control.
Santi Cazorla opened the scoring from the penalty spot after Alexis had been poleaxed in the area, before the Chilean added a second himself.
With Arsène Wenger’s side in fine fettle, their third - on the stroke of the interval - was richly deserved as Mesut Ozil thumped a header beyond former Tottenham goalkeeper Heurelho Gomes.
