Besiktas came away 1-0 winners on the road in the first leg, despite dropping down to 10 men for the final 18 minutes of the contest.
They probably should have scored a few more goals in the first leg having taken 22 shots and registering an xG 2.33.
I also feel as though the underdogs missed their chance in the first leg, they failed to score in front of their own fans from nine shots on target - prompting a man of the match performance from Alexander Nubel in goal.
Besiktas only lost four of their 17 home games in the Super Lig last season and have won each of their last three qualifying games as part of the Europa League campaign.
