Eddie Nketiah scored the winner as Arsenal opened 2017 with a 2-1 victory over Derby County.
In a match between the two sides promoted from Division 2 last season, Savvas Mourgos opened the scoring at London Colney after only six minutes.
But Derby equalised seven minutes after half-time through Timi-Max Elsnik but Nketiah, who came on at half-time, struck to lift Arsenal to fifth in the Division 1 table. Derby remain bottom.
