Alexandre Lacazette boosted Arsenal hopes of finishing in the Premier League top four with a 1-0 narrow win over West Ham at Emirates Stadium on Saturday evening.

The Frenchman goal 1 found back of the net 12 minutes from time, which was confirmed by the video assistant referee, lifted the Gunners up to ninth, five points behind Chelsea in fourth.

West Ham, who enjoyed the better of the goalscoring opportunities until that point, remain 16th, above the bottom three only on goal difference.
