Arsenal reclaimed fourth place in the Premier League after beating Leicester City 2-0 on Sunday evening.
The Gunners were unchanged, as Bukayo Saka and Gabriel Martinelli flanked Martin Odegaard in a front three just behind lone-striker Alexandre Lacazette while Leicester were without the injured Jamie Vardy, as Kelechi Iheanacho returned to lead the line.
Mikel Arteta's charges had a dream start after Thomas Partey gave them the lead in the 11th minute with a flicked header at the near post from Martinelli's inswinging corner.
Arsenal were taking the game by the scruff of the neck and Partey came close to doubling their lead in the 18th minute with a strike towards the top corner that came off the crossbar.
However, Brendan Rodgers' men were getting into the game in the latter stages of the first stanza but they did not create clear-cut chances, as the Gunners entered the halftime break with a narrow lead.
Here are the highest-paid players in the Premier League this season:
Arteta's men were causing Leicester all sorts of problems coming from the half-time break and Luke Thomas thought he had kept the visitors in the game ten minutes into the second stanza after clearing Partey's header off the line.
However, the Gunners were awarded a penalty belatedly after a Video Assistant Referee (VAR) review spotted a handball by Caglar Soyuncu from that phase of play and Lacazette gave the hosts a two-goal cushion with a strike that flew into the top corner.
Leicester needed fresh legs upfront with 16 minutes remaining, as Patson Daka replaced Iheanacho and four minutes later Arsenal also made an attacking change, as Emile Smith Rowe replaced Martinelli.
As the game opened up, Smith Rowe almost put the game to bed for the hosts in the last eight minute with a strike from a tight angle but goalkeeper Kasper Schmeichel smothered his effort, as the Gunners saw out a comfortable win that sent them up to fourth on the log with three games in hand.
