Darnell Johnson's own goal gave Arsenal their fourth win in five Premier League 2 matches this season as they beat Leicester City to join Liverpool at the top of Division 1.
After the visiting Leicester side had the better of the opening half hour, Jordi Osei-Tutu's right-wing cross was turned into his own net by Foxes defender Johnson.
Arsenal striker Eddie Nketiah tested Leicester goalkeeper Daniel Iversen twice either side of half-time, before Keirnan Dewsbury-Hall was denied an equaliser by a brilliant save from Matt Macey.
The Gunners visit defending champions Everton in their next PL2 match on Monday 25 September. Three days earlier, Leicester host Chelsea.
