Darnell Johnson's own goal gave Arsenal their fourth win in five Premier League 2 matches this season, beating Leicester City 1-0 to join Liverpool at the top of Division 1.
After Leicester had the better of the opening half-hour at Boreham Wood, 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 Everton in their next PL2 match on Monday 25 September. Three days earlier, Leicester host Chelsea.
