Pierre-Emerick Aubameyang scored a 10-minute hat-trick as Unai Emery started his Arsenal reign with an 8-0 friendly win over National League side Boreham Wood.
Emery was appointed Gunners manager in May after Arsene Wenger's 22-year spell in charge came to an end and the Spaniard could not have wished for a more comfortable first game in charge.
It was Wenger's last signing as Arsenal boss who was the star turn during a goal-laden first half on Saturday.
Aubameyang, who arrived from Borussia Dortmund during the January transfer window, plundered 10 goals in 13 Premier League games towards the end of 2017-18 campaign and wasted little time picking up where he left off.
