The Gunners moved four points clear of fifth-placed Manchester United.
Two first-half goals from Alexis Sanchez did the damage as Arsene Wenger's side leapfrogged Manchester City into third place in the table, consolidating a Champions League qualification spot in the process.
The Gunners sit four points clear of fifth-placed Manchester United, with four games to go, and it would appear as if Arsenal are on course to maintain their stellar record of qualifying for Europe's elite competition.
They could, and probably should, be aiming higher, but a 1o-point gap from Leicester City at the summit means they will almost certainly miss out on the Premier League title for a 12th successive year.
It has, in truth, been a disappointing season for Arsenal and one which will fail to produce trophies. Having won back-to-back FA Cup crowns in 2014 and 2015, it was suggested that they would look to the title this time around, and what a chance they had, but the Gunners ultimately fell away on the hunt.
They visit relegation-threatened Sunderland tomorrow.
