Arsenal registered a fourth successive victory in the Premier League after defeating Watford 3-2 at Vicarage Road on Sunday.
Arsenal decided against making any changes from their late win over Wolverhampton Wanderers in their last encounter in the league.
It was vindicated with five minutes played as Martin Odegaard made the opening when he finished off a one-two with Bukayo Saka.
Watford levelled it up six minutes thereafter when Cucho Hernandez attacked a telling cross into the danger area and applied a solid overhead kick finish past Aaron Ramsdale.
The Gunners restored their lead towards the halftime period through Saka, who played a give and go around the area with Alexandre Lacazette before finding the back of the net.
Here are the highest-paid players in the Premier League this season:
With no halftime substitutions from either side, the Gunners extended their lead minutes into the restart as a number of one touches led to Gabriel Martinelli who took aim and fired home.
The Gunners were in the mood to add more goals late in the second half and it showed with the attacking introductions of Nicolas Pepe and Eddie Nketiah.
It was almost justified nine minutes from time when the latter got involved in a counter-attack to go clear and get a shot away that came off the upright.
However, a nervy finish followed them after Moussa Sissoko controlled a looping ball into the area on the chest to bundle home with three minutes to go.
Although, the Gunners didn’t crack under the late pressure from Roy Hodgson’s men but managed their advantage and confirmed victory.
