Arsenal finished in first place in Champions League Group A after beating Basel 4-1, while Paris Saint-Germain settled for a surprise home draw to close out the group stage on Tuesday.
Lucas Perez recorded a hat trick inside 47 minutes before Alex Owobi added a fourth to help the Gunners on their way to a dominant victory.
Arsenal needed just eight minutes to open the scoring at St Jakob-Park, with Kieran Gibbs squaring the ball to Perez after being played in by Alexis Sanchez and the Spaniard then converting from close range at the far post.
By the 16th minute the Gunners were two goals up after Perez added his second of the night, tapping home the rebound from just a few yards out after Gibbs’ strike was saved by Tomas Vaclik.
It was 3-0 two minutes after the restart, with Perez firing past Vaclik into the bottom corner to complete his hat trick after Gibbs’ pass was diverted into his path by Sanchez.
And it was four for Arsenal just seven minutes later when Iwobi slotted home from close range after Mesut Ozil had pulled the ball back across goal to him, before Basel found a consolation goal through Seydou Doumbia.
PSG entered the final matchday level with Arsenal on 11 points, but the French side’s head-to-head advantage would not come into play as they could only manage a 2-2 draw at home with Ludogorets Razgrad.
Virgil Misidjan headed home from Natanael Pimienta’s curling cross in the 15th minute as the Bulgarian side secured a spot in the Europa League as third-place finishers.
Edinson Cavani found the equaliser after the hour mark, converting a bicycle kick from close range after a missed defensive clearance.
But just as a winner for PSG seemed inevitable, Ludogorets took the lead for a second time on 69 minutes as Cafu dispossessed Marquinhos and pulled a pass back for Wanderson to score.
Ludogorets were denied a famous victory as Angel Di Maria scored in stoppage time, but PSG could not find a winner in the final moments and finished second in the group.
