Hector Bellerin sent a message to former Arsenal forward Serge Gnabry after he netted four in Bayern Munich's 7-2 hammering of Tottenham on Tuesday.
"Joke man," wrote Gunners right-back Bellerin on Twitter , alongside four laughing face emojis as he watched the German giants tear Spurs apart in the Champions League.
Like Bellerin, Gnabry came through the youth ranks at Arsenal after joining the Emirates club as a youngster from Stuttgart all the way back in 2012.
He made a handful of appearances in England, and was sent on loan to West Brom in 2015, but failed to shine under then Baggies manager Tony Pulis.
Arsene Wenger opted to sell the young German, and Werder Bremen were only too happy to part with just £5million to land the forward.
After just one season back in January Gnabry had caught the eye of Bayern Munich and completed a transfer to the Bundesliga giants.
On Tuesday he returned to north London for Bayern's Champions League group clash with Arsenal's bitter rivals Tottenham.
And it's save to say the 24-year-old embarrassed them with four goals in the 7-2 victory.
