Alexandre Lacazette was delighted to prove the match-winner against Olympiacos on Thursday.
Lacazette's second in as many games gave Arsenal a valuable away goal in the 1-0 victory in Greece.
The Frenchman told BT Sport: "It was a good performance. We had a clean sheet, that's a good point. We wanted to score more goals but in the end it is good because we have an advantage for the second leg.
"I had a few chances but it's not always easy to score. Thanks to Bukayo Saka for the assist, it was nice. I'm happy to score.
"It was nice to come here with the great atmosphere and now we go home with our fans and it will be good."
