Arsenal turned on the style to thrash Burnley in Arsene Wenger's final home game as manager.
The 68-year-old, who has won 10 major trophies during a near 22-year reign, oversaw a dominant, free-flowing display in his 1,233rd game, with slick first-half goals from Pierre-Emerick Aubameyang and Alexandre Lacazette.
Sead Kolasinac scored with a powerful low drive after the break, and another was started and finished explosively by Alex Iwobi, one of 83 academy graduates to come through the ranks under Wenger.
Aubameyang got his second from close range to complete the rout.
Listless Burnley, who had their Europa League qualification confirmed on Saturday, lost striker Ashley Barnes to a 22nd-minute suspected dislocated shoulder, but will nevertheless finish an impressive campaign in seventh.
Wenger was given a guard of honour by both teams before kick-off and, in quotes tweeted by the club, urged supporters, some of whom have long called for his exit, to "no matter what, keep the faith".
Fans of both sides frequently chanted "There's only one Arsene Wenger", and Arsenal's supporters also sang the name of former midfielder Patrick Vieira, who has been among the names tipped to take over at the Emirates next season.
