Arsenal qualified for the knockout stages of the Europa League after beating Molde 3-0 with Nicolas Pepe redeeming himself after his Elland Road red card.
Pepe, whose headbutt on Ezgjan Alioski on Sunday was called “unacceptable” by his manager Mikel Arteta, was given an immediate chance to make up for his misdemeanour by starting in Norway and opened the scoring with a fine curling effort (50).
Reiss Nelson was on hand to hammer home from close range (55) before substitute 19-year-old Folarin Balogun netted his first goal from the club having been on the pitch for just 37 seconds (83).
Arsenal started with plenty of tempo and adventure with at times the wide men making it a front four.
They dominated the early territorial battle but it was the hosts that created the most dangerous opening when Magnus Eikrem half-volleyed a quite brilliant ball across the face of goal for centre-back Sheriff Sinyan at the far post but he side-footed it back across goal and Alex Runarsson made a save.
