The Italian champions held a 4-0 advantage from the opening game in Italy three weeks ago, but only managed to scrape through in the end as first-half goals from Laurent Koscielny, Tomas Rosicky and Robin van Persie gave the Gunners a 3-0 victory in the return leg. \"We are relieved to go through, especially since we came in at half-time 3-0 down,\" Emanuelson told Uefa.com. \"The plan was to just play our own game. We didn\'t want them to score in the first 15 minutes, but we made a mistake early on with the corner and suddenly it was 1-0. \"We didn\'t play a good first half but we still had faith and trust in our team that we could get a good result. \"We just kept in our minds that we only needed one goal. We improved in the second half and we can be happy about it because they only had one big chance for Robin [van Persie].\" Having sneaked into the last eight of the Champions League, the Rossoneri\'s next assignment is a Serie A encounter with Lecce at San Siro on Sunday.
