Arsenal found a last-gasp winner against promoted Luton to move five points clear at the top of the English Premier League. The Gunners broke the deadlock at Kenilworth Road with Gabriel Martinelli finishing a Bukayo Saka move. Gabriel Osho's header brought the hosts level shortly after, then Gabriel Jesus made it 2-1. The Hatters threatened to beat the leaders when Elijah Adebayo and Ross Barkley scored in a frenetic eight-minute period in Bedfordshire. But Declan Rice's last-gasp header in the stoppage time gave Mikel Arteta's team yet another scrappy away win. Arsenal have 36 points from 15 matches while Luton, 17th, have nine from their 15.
