Aubameyang: 'I knew scoring would be good for Lacazette's confidence so I gave penalty to him'
Despite scoring a brace, the forward admitted that the game wasn't easy for the Gunners.
"It was not easy. It is not always easy after an international break. We did a good job.
"I felt a little bit under pressure (when taking the penalty after missing against Manchester City) but I was just thinking I had to score and I needed to focus.
When asked why he didn't take the second penalty: "I know Alexandre Lacazette is back and I had scored twice already so I knew it would be good for his confidence."
