Pierre-Emerick Aubameyang's 18th Premier League goal of the season downed Watford and sent Arsenal up to fourth in the table but their dismal away form continues.
2018/2019 Premier League
Arsenal recorded their first away clean sheet in the Premier League this season with Ben Foster's mistake and Troy Deeney's red card contributing to a 1-0 victory for the Gunners at Watford.
Unai Emery's side have struggled for form on their travels in all competitions but were gifted three points at Vicarage Road on Monday, moving them up to fourth in the table.
Foster's lapse in concentration saw Pierre-Emerick Aubameyang score his 18th league goal of the campaign in farcical fashion in the 11th minute, with Deeney then almost immediately dismissed for an elbow on Lucas Torreira.
FA Cup finalists Watford impressed despite being reduced to 10 men, full-back Adam Masina clipping the crossbar with a superb drive in the second half, but they succumbed to their first home defeat of the year.
10' GOAL! Watford 0-1 Arsenal (Aubameyang)
A nightmare for Foster! He dwells on the ball and his clearance ricochets off Aubameyang and into the net!
11' Red Card! Deeney sent off
Deeney is shown a straight red for an elbow into the face of Torreira. As Alan Smith says on commentary: "It's a silly challenge."
20' What a save from Leno!
Cathcart smashes a fierce shot on goal from close-range on the half-volley, forcing Leno into making a smart save with his left leg!
26' CHANCE! Iwobi's shot denied
Arsenal counter and Iwobi hits a left-footed shot on goal aiming for the top corner which Foster acrobatically parries behind!
32' Another great save from Leno to deny a free-kick shot!
It's a fine strike from Capoue who curls his free-kick around and over the wall. There's some whip on it but Leno does spectacularly well to get to it with an outstretched left arm!
56' WHAT A SAVE! Mkhitaryan's shot denied by Foster
Arsenal counter with four players surging forward. Iwobi picks out an unmarked Mkhitaryan at the far post, but his side-footed volley is excellently stopped by Foster's right boot!
62' OFF THE BAR! Nearly a screamer for Watford!
Masina unleashes a venomous drive from 30-yards out which crashes off the woodwork! That was a fantastic effort! Wow.
