Gabriel Martinelli scored two goals and set up another as a heavily rotated Arsenal side turned on the style to thrash Standard Liege 4-0 in their Europa League Group F meeting at the Emirates Stadium.
Teenager Martinelli, a £6m signing from Brazilian side Ituano during the summer, opened the scoring with a superb header after 13 minutes and netted his second with a low, curling finish just three minutes later, making it four goals from two games following his double against Nottingham Forest in the Carabao Cup.
