Aubameyang's 18th goal of the Premier League season was enough for Arsenal to secure three points at Vicarage Road.
Pierre-Emerick Aubameyang was happy his goal handed Arsenal a vital over Watford on Monday night.
The Gunners moved back into the Premier League top four with a 1-0 win over The Hornets as Pierre-Emerick Aubameyang's 18th league goal was enough for Unai Emery's men to claim three points.
The visitors took the lead with just 10 minutes into the game, thanks to an error from goalkeeper Ben Foster, who received a pass back and proceeded to hit the ball against Aubameyang - and the ball rebounded into the net.
The win at Vicarage Road was the Gunners' first clean sheet of the season and following the match against 10-man Watford, the Gabon international told Sky Sports: "It feels good tonight because away is always difficult for us but the team did a great job and everybody fought for the three points. Today we are really happy.
“We knew it would be a tough game and everybody knows what the target is for us this season – to get the top four - and it is really important to stay in the competition for the top four. We did a great job.”
Liverpool legend Jamie Carragher said of the striker, who scored his first away from home since Boxing Day: "I think Aubameyang was really brave. Sometimes when you dangle that ankle out, and the keeper's in full stride clearing it, I think he was quite brave.
"He’s come in like a superstar from Borussia Dortmund. He doesn’t play every game, but for me, I still can’t believe he doesn’t play Aubameyang and Lacazette in away games, even against a 10-man Watford."
