Unfortunately for the Blues, it wasn't their day at Wembley after they went down 2-1 to Arsenal as the curtain finally came down on the doemstic season.
Pierre-Emerick Aubameyang's double helped the Gunners come from a goal down after Christian Pulisic's early strike.
And after Werner completed his big-money switch from RB Leipzig in June, his former club just could not resist a cheeky parting shot.
Fresh from their defeat at Wembley, the Bundesliga outfit decided to poke fun at Chelsea, posting an image to Twitter which appeared to imitate Werner texting his former colleagues.
The message read: "Timo Werner is typing...", insinuating that the German forward wanted to return to his native land after Chelsea's defeat.
Of course, this was all in jest with the two clubs sharing a good relationship and sending well wishes to each other after concluding the £47m deal.
But Werner will certainly be hoping he can contribute to silverware in the near future as he prepares for his Premier League adventure.
If not, Chelsea may actually have to worry about losing him at some point in the future.
