Alexandre Lacazette, Nicolas Pepe, Folarin Balogun and Calum Chambers were all on target as Arsenal strolled to a 4-1 win over Millwall in a friendly, while new signing Albert Sambi Lokonga got his first taste of action in a Gunners' shirt.
Chambers put Arsenal in front in the first half by tapping into an open goal after Pierre-Emerick Aubameyang had blasted against the bar with an overhead kick.
Coach Mikel Arteta brought on Lokonga, who joined Arsenal from Anderlecht earlier this month for £15million, while also introducing Lacazette, Nuno Tavares and Karl Hein.
