Arsenal moved five points clear at the top of the Premier League after a hard-fought 1-0 win over relegated Burnley at home on Monday night.
Kai Havertz's first-half header proved decisive at the Emirates. It was enough to secure three crucial points for Mikel Arteta's side.
The Gunners controlled much of the contest. They created numerous chances but struggled to add to their single goal.
Arsenal now sit on 82 points with one match remaining. Manchester City, who face Bournemouth tomorrow, trail them by five.
If City slip up against Bournemouth, Arsenal will be crowned champions for the first time since 2004. Otherwise, Arteta's men must beat Crystal Palace in their final game on Sunday to claim the title.
Arsenal's relentless pursuit of silverware has captivated English football this season. One win now separates them from ending a 22-year drought at the top.
