Christian Fuchs’ own goal and Eddie Nketiah’s stoppage-time goal was enough for the Arteta’s men to book their place in the 4th round of the competition.
Operating as a left wing-back, Saka produced an eye-catching performance, threatening the Leicester defense with his raids.
The youngster was unfortunate not to be awarded a penalty when bundled to the ground by Amartey but he will settle with the win – and another display that enhanced his growing reputation at Arsenal and beyond.
Saka was rated 8/10 at the end of the game, most by any player who featured in the game.
He already two assists for the Gunners this season and has only missed a game so far.
