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