Arsenal manager Unai Emery has reiterated the Europa League's importance to the club.
The Gunners made it three wins from three in the group stage on Thursday night by beating Vitoria 3-2 at the Emirates.
"A lot happened over 90 minutes," Emery said. "The Europa League is very important for us and our aim is to finish first in the group. In the first half, we struggled more than we wanted, we lost a lot of balls in the middle and given them chances in the transition to score and start winning the match.
"The second half we controlled the match better and we had good chances... I think we deserved to win, but Vitoria played well. Every Portuguese team are very organised teams, they have a very good structure and good players.
"There are more positive things than negative things and I want to take the positive things tonight for the next matches."
