Arsenal can have some sympathy with Red Bull Salzburg.
Five years ago, in what remains their last appearance in the Champions League to date, the Gunners suffered a humiliating last-16 second leg defeat at the hands of Bayern Munich.
Already trailing 5-1 from the Allianz Arena, Arsenal lost by the same scoreline in the return meeting at the Emirates Stadium on March 7, 2017 to be eliminated 10-2 on aggregate.
