After Manchester City dropped points away at Newcastle, it was over to Arsenal to take advantage.
It looked like they were on course to do just that at home to Leicester City, a side who had failed to win a single game in the Premier League this season.
But then up stepped James Justin for the Foxes, pulling one back after 47 minutes.
Then, minutes later, he silenced the crowd at the Emirates with a stunning strike on the volley as he stood unmarked in the penalty area just after the hour mark.
His one-time hit curled out to the left and beat a diving David Raya for 2-2.
Can Arsenal regain the lead?
