The Gunners ended their impressive pre-season campaign in style with yet another win in a dominant display in front of their home fans.
Bukayo Saka put the North London side in front after just 10 minutes, converting the penalty he won clinically.
Thereafter, Gabriel Jesus scored twice in the space of 60 seconds, the first coming from a rebounded Gabriel Martinelli shot and the other coming from a cross from the fleet-footed Brazilian winger.
Saka then capitalized on some comical defending to get his brace, then Jesus sealed his hat-trick in the second half before going off.
Substitute Eddie Nketiah added to Sevilla’s woes with a simple finish from a Martinelli pass.
Elsewhere, Manchester United succumbed to a 1 – 0 loss to Atletico Madrid who scored late on through Portuguese youngster Joao Felix.
