On route to the trophy last season Claudio Ranieri’s side only failed to score in three matches but were held as both defences stood out, with the Arsenal back line strengthened by the return of Laurent Koscielny, while Robert Huth also started for the first time for the defending champions.
Jamie Vardy raced into Arsenal’s penalty box within the first minute and forced a last-ditch clearance from the Arsenal back line.
Alex Oxlade-Chamberlain provided Arsenal’s first real opportunity, cutting in from the left and whipping a long range strike narrowly wide of the far post.
Petr Cech raced off his line to block out Riyad Mahrez’s sublime through-ball and Leicester’s claims for a penalty when Danny Drinkwater fell under the challenge of Laurent Koscielny were waved away by referee Mark Clattenburg.
Leicester’s hopes were hit when new signing Nampalys Mendy was forced off during the first half after twisting an ankle.
As the game opened up in the second half, Mahrez curled a ferocious free-kick just over the bar before Vardy latched on to Marc Albrighton’s delivery but his shot cannoned well wide.
Cech was called upon once again in the closing stages, smothering a close-range Mahrez effort from the right, as Arsenal, a week after conceding four goals to Liverpool, gained a vital point.
