Arsenal moved a step closer to winning their first Premier League title in 22 years, beating relegated Burnley 1-0 and putting the pressure on Manchester City heading into their penultimate match on Tuesday.
Knowing they could take a giant step towards history, Arsenal showed patience in building the game for the go-ahead goal.
The first clear chance came when Leandro Trossardi created space and fired powerfully at the near post from outside the area, while Eberechi Eze registered the first shot on goal with a volley from distance.
Mikel Arteta reacted angrily when Bukayo Saka was denied a penalty after a challenge on Lucas Pires, while Martin Ødegaard's shot from inside the area was deflected just wide.
The goal came from a set piece situation – and was Arsenal's 18th goal of the season from a corner kick, a new record.
Kai Havertz rose above everyone in the area and scored with a header, also providing Bukayo Sakas with his 50th Premier League assist.
Arsenal continued to search for a second goal in the second half, with Eze hitting the crossbar after a slight deflection by goalkeeper Max Weiß.
Havertz also came close to a red card for a challenge on Lesley Ugochukwu, but escaped punishment.
Despite the pressure at the end, Arteta's team settled for a minimal victory, taking three very important points.
A third successive 1-0 win means any mistake by Manchester City against Bournemouth on Tuesday could hand Arsenal the title before their final game against Crystal Palace, giving them more time to prepare for the Champions League final.
Meanwhile, Burnley must win against Wolves next week to avoid the club's record of lowest number of wins in a Premier League season.
Arsenal now have 82 points after 37 games, five more than City who have 77 points, but with one game less./Express newspaper/
