Teenage striker Gabriel Martinelli scored two goals and set up another to give Arsenal victory over Standard Liege in the Europa League.
There was less than three minutes between the 18-year-old Brazilian’s first and second goals while team-mate Joe Willock, 20, made it 3-0 before half-time.
Martinelli, who joined for £6m this summer, later set up Dani Ceballos for his first Arsenal goal.
Arsenal sit top of Group F with two wins from two games.
There were 10 changes to the Arsenal team who drew with Manchester United in the Premier League on Monday but no place in the squad for German midfielder Mesut Ozil.
