Unai Emery has defended his sides poor performance in recent weeks after a 1-0 win over Watford.
Pierre-Emerick – Aubameyang scored the only goal of the match for the Gunners and maintaining hopes of his team for the four contentions in the Premier League.
However, Emery knows his side needs to perform well in the second leg of the Europa League against Napoli if they want to make to the semifinals.
The three points is, I think, the most important thing today,” he said.
“But also, I think we worked well being consistent in our structure, defending their long balls and set-pieces.
“Here they are a very strong team at doing that. After, with the ball I wanted to do better, I wanted to control better with the possession of the ball and with one player more on the pitch.
“We needed to defend in the last minutes, very close with everybody to their good action in the long balls, and the second action to be good in defensive moments.”
