Alexandre Lacazette scored either side of Gabriel Martinelli's first of the season as we picked up a much-needed victory at Bramall Lane.
Lacazette's first came at the end of an excellent team move, with Dani Ceballos flicking the ball through for Laca to tuck home.
Martinelli doubled the lead in the second half after tucking home from close range when Nicolas Pepe's shot was parried.
We sealed the win late on through Lacazette, who raced on to an excellent Thomas Partey pass from midfield, and confidently netted his 50th Premier League goal for the Gunners.
