Leicester City beat 10-man Arsenal 3-1 at the King Power as Arsene Wenger's side remained without an away league point in 2018.
Leicester opened the scoring after just 14 minutes thanks to Kelechi Iheanacho's second league goal of the season, before the striker was then brought down by Konstantinos Mavropanos when clean through on goal.
The young Greek defender was shown a straight red card by referee Graham Scott, Arsenal's 78th sending-off in the Premier League under Wenger, only for Pierre-Emerick Aubameyang to level matters eight minutes after half-time.
However, the home team took all three points thanks to Jamie Vardy's 76th-minute penalty - the striker's sixth goal in seven games against Arsenal - and Riyad Mahrez's last-minute effort.
As a result, the Foxes stay ninth in the table thanks to a first top-flight win in six matches, while Arsenal remain sixth.
