Chelsea fans have jumped at the chance to poke fun at Arsenal after Petr Cech's latest tweet on the anniversary of their 4-1 Europa League final victory.
The Blues ran out victorious in Baku on May 29, 2018, securing the Europa League title against their London rivals and denying them a place in this season's Champions League final.
In what turned out to be Eden Hazard's last appearances for Chelsea, it was also the end of Cech's career too.
The goalkeeper, so famous for his heroics at Stamford Bridge, ended his career with the worst possible swansong, a 4-1 drubbing against his former club.
Many Arsenal fans were left baffled by Unai Emery's decision to pick Cech for the final, given the game's importance, with Bernd Leno established as the number one goalkeeper.
Arsenal's defence crumbled in the second half, with Cech helpless to deny four Chelsea goals flying past him, with only one at the other end from Alex Iwobi.
On the one year anniversary of the match, Cech wrote: "Year has gone but the pain remains .... @Arsenal #europaleaguefinal... last game of the career 29/5/2019."
As you might imagine, given his Chelsea connections, Blues fans have jumped on the tweet to remind him of his loyalties to the blue half of London.
Here's a round-up of what they had to say.
Cech finished his career with 18 trophies to his name.
