Arsenal finished top of Champions League Group A thanks to a Lucas Perez hat-trick in Basel and
Paris St-Germain would have sealed top spot with victory, but was held to a draw by Luff15 enogorets Razgrad.
Arsene Wenger’s side failed to make it past the last 16 that year, and have fallen at the first knockout stage in each of the past six seasons.
Aside from breaking their run of second-placed group finishes, the Gunners have also gone through a group stage unbeaten for the first time since they reached the final in 2005-06.
Spaniard Perez has struggled to make an impression since a £17m move from Deportivo La Coruna in August, making just one Premier League start and only finding the net with a double against Nottingham Forest in the League Cup.
This hat-trick definitely cemented his place with the club.
