Chelsea aimed a brutal dig at Arsenal immediately after the Gunners lost the Champions League final on penalties to Paris Saint-Germain.
Arsenal took the lead on six minutes through Kai Havertz, with PSG struggling to break them down throughout the rest of the first half.
But the defending champions won a penalty in the second half after Cristian Mosquera brought down Khvicha Kvaratskhelia, with Ousmane Dembele converting from the spot on 65 minutes.
Extra time came and went without any goals, with Viktor Gyokeres coming close with one of the final opportunities of the game when his shot was deflected behind for a corner.
PSG kicked first in the shootout, and Eberechi Eze missed with Arsenal's second spot kick when he placed his effort wide of the post.
David Raya then saved well to his left to deny left-back Nuno Mendes.
Gabriel Magalhaes took Arsenal's fifth penalty to tie the shootout at 4-4 and force sudden death, but the Brazil centre-back blazed his penalty over the bar.
It was a devastating outcome for the Gunners, who were looking to win the first Champions League trophy in the club's history.
That fact wasn't lost on Chelsea, who aimed a post-match dig at the Gunners via their Instagram page.
The Blues, who finished ninth in this season's Premier League and won't play European football at all next term, posted an advertisement for Stamford Bridge stadium tours - including a visit to what they described as 'London's Home of Trophies'.
Chelsea won the Champions League final - on penalties - against Bayern Munich in 2012 under the management of Roberto Di Matteo.
"Come and visit London's Home of Trophies," they wrote on Instagram.
"Book your Stadium Tour at Stamford Bridge now via the link on our story or in our bio."
The Blues posted photos of their Champions League trophy and also the Club World Cup title, which they won last summer under Enzo Maresca.
While Chelsea may have had a nightmare season since then, they have appointed Xabi Alonso as their new manager starting from July 1.
The Spaniard is expected to have more control over transfers and other key decisions than his predecessors under Blueco, the club's current owners.
