The Gunners cruised past their Portuguese opponents and into the last eight of the Champions League with a 6-2 aggregate win without captain Cesc Fabregas.
The Spain midfielder missed the tie with a hamstring injury, leaving Nicklas Bendtner to score a hat-trick and Samir Nasri and Emmanuel Eboue to weigh in with goals.

'We are a team first,' said Sagna. 'It's not about one player, even though Cesc is very talented. We showed that everyone can play.
'Of course, Cesc is welcomein the team, he's the captain, which means a lot, and he's a very goodplayer. But we're approximately 25 players at Arsenal, so we play as ateam.
'It was quite difficult tonight, we had to win if we wanted to gothrough. But we were able to score quitequickly and the game became a bit easier for us. We kept pressurisingand that was important. You have to congratulate the team forwhat we did.'
