Pierre-Emerick Aubameyang’s early goal guided the Gunners back to the title race after a clean sheet 1-0 win in a drama-filled Monday clash. They climbed two places to the fourth spot with 66 points, two points clear of Manchester United and ahead of Chelsea on goal difference.
Aubameyang took the opportunity to steal a cheeky goal in the 10th minute thanks to a blunder made by the Hornets goalkeeper Ben Foster. He charged down Foster, who failed to clear a pass from defender Daryl Janmaat.
Besides 1-0 down, Watford suffered the heavy blow at the Vicarage Road when Troy Deeney was shown a straight red card few seconds after the goal.
The Hornets captain caught Lucas Torreira with his elbow as he ran past the midfielder. The home crowd saw the nightmare when referee Craig Pawson consulted with his assistant and showed him the red card.
It was Deeney’s second red card in the Premier League and the first time since December 2017 against Huddersfield.
Watford gave full efforts for the whole 90 minutes but ran out of the luck as they missed chances of hitting the target.
Since his debut in February 2018, Aubameyang has scored 28 goals and made nine assists for Arsenal.
The win means Arsenal have their first away clean sheet in the league this season at the 16th time, while the Hornets suffered their first defeat in six league home games.
