Manchester City's chances of winning the Premier League increased ever further on Sunday as their two nearest rivals both failed to win.
However, in a truly forgettable game with virtually no clear chances, Man United and Chelsea played out a goalless draw at Stamford Bridge.
The result means that United now find themselves 12 points behind Pep Guardiola's men with 12 games remaining this season.
Youri Tielemans gave Leicester an early lead but Arsenal turned the match around with goals from David Luiz, an Alexandre Lacazette penalty and Nicolas Pepe strike.
The Gunners move back into the top-half of the table but they are still eight points off the Champions League places.
Liverpool, though, are back in the top-four race as they ended their four-game losing streak by winning 2-0 at rock-bottom Sheffield United.
A Curtis Jones goal and a Kean Bryan own goal did the damage against a Sheffield United team that now seems destined for relegation.
Gareth Bale capped off an excellent week with two goals and an assist. Harry Kane and Lucas Moura grabbed the other goals.
