It was a night to forget for Tottenham Hotspur.
Spurs were hoping to pit their wits against one of Europe's top sides to show that they were truly capable of rubbing shoulders with the best, but alas, that wasn't to be.
Despite a competitive first half, the wheels came off for Mauricio Pochettino's side who went on to lose 7-2 to Bayern Munich on their home turf.
Joshua Kimmich opened the scoring for the German side, while Robert Lewandowski scored a brace as well, but it was a former Gunner who stole the headlines.
Serge Gnabry moved to Arsenal when he was 16 where he moved through the age groups in north London.
Despite showing early promise, the winger was unable consistently force his way into Arsene Wenger's plans, instead leaving the club for Werder Bremen in 2016.
But fast-forward three years, and the German star - who now plays for Bayern - scored a staggering four goals past Arsenal's north London rivals in the biggest competition in Europe.
Not only did he score the goals which secured such a one-sided victory, but Gnabry's four goals means that he has now scored as many goals at the Tottenham Hotspur Stadium as Spurs talisman Harry Kane.
Talk about kicking Mauricio Pochettino's side when they're down.
