Raheem Sterling struck in the second minute to give leaders Manchester City a 1-0 win at Arsenal, their 13th consecutive Premier League victory.
Sterling leapt high to nod in Riyad Mahrez's right-wing cross and it proved to be decisive as Man City opened up a 10-point lead over Leicester City at the top of the table.
Sterling could have scored twice more in the first five minutes while Ilkay Gundogan was denied by Bernd Leno, who tipped away his 56th-minute shot.
At the other end, Mohamed Elneny drove wide after some hesitancy in the City defence with 17 minutes left.
City are now unbeaten in 17 Premier League matches and move on to 59 points. Arsenal stay 10th on 34 points.
