The first leg of the tie, which finished with Lyon earning a 2-1 home win, was wrecked by violence in the stands.
Both clubs have since been handed suspended bans from European competition by Uefa after their match was suspended by 45 minutes due to trouble in the stands.
Thankfully, however, tonight’s match has been all about the football on the pitch, with Lacazette earning all the plaudits for a magnificent chip over an on-rushing Besiktas goalkeeper:
✅ Fantastically worked
✅ Fantastically finished
Alexandre Lacazette makes it 29 goals this season. Unreal form! ?? pic.twitter.com/X92b8uAuNd

The Frenchman’s strike cancelled out Souza Conceicao’s opener for the hosts, meaning the score is now 3-2 on aggregate to Lyon with little over half an hour still to be played.
