The Gunners are just two points off top spot after extending their winning run in all competitions to 10 matches in a row thanks to an excellent second-half performance against Leicester City.

Arsenal probably should have had a fourth, but Lacazette's look on the doorstep was smothered well by Schmeichel. That signing of Bergkamp revolutionised the club and took them to titles.
Arsenal were slow out the blocks and Leicester were unlucky not to get a penalty when Rob Holding handled in the area but they eventually got the luck they deserved when Ben Chilwell's effort defected past Bernd Leno via Hector Bellerin's boot in the 31st minute.
Schmeichel kept out a dipping Granit Xhaka free kick in the period that followed, before the Leicester goalkeeper had to keep out a strike from Alex Iwobi as the home side chased for a leveller before the break.
