Arsene Wenger saw his Arsenal side win their first Premier League game of the season with a comfortable 3-1 victory at Watford before insisting there is more to come from his players as they close in on two new recruits.
An early Santi Cazorla penalty was added to by Alexis Sanchez and Mesut Ozil as the Gunners raced into a commanding first-half lead at Vicarage Road.
They visibly tired after the interval and Watford pulled a goal back as club-record signing Roberto Pereyra scored a debut goal, but the hosts could not find a way to set up a grandstand finish.
