New signing Gabriel Magalhaes grabbed a debut goal and Pierre-Emerick Aubameyang scored a stunner in Saturday season’s opener, while former Chelsea winger Willian provided a pair of assists on his debut, just 48 days after the last season ended.
Arsenal’s free-flowing attack was too much for promoted Fulham as Lacazette gave the visitors an early lead.
Brazilian defender, Gabriel, scored Arsenal’s second after the break in his first appearance since joining from Lille.
Aubameyang then added the final flourish with a typically eye-catching strike.
It was the ideal way for Arsenal to start a season that appears full of promise after last season’s FA Cup triumph.
The Gunners beat Premier League champions Liverpool on penalties in the Community Shield last month and also won the FA cup last season.
