Arsenal stated scoring quickly with Jesus curled in a superb goal to give the host the lead, before nodding in from close range to make it two.
Gunners were in command at half-time, but Leicester pulled one back when Saliba headed into his own net, which was an honest mistake.
The hosts reacted quickly, though, with Jesus setting up Xhaka following a mistake from Ward.
And the pattern repeated itself when Maddison pulled one back, only for Martinelli to restore the two-goal advantage with a precise finish.
