RB Leipzig have enjoyed a cheeky swipe at Liverpool after keeping hold of Naby Keita last month.
The midfielder is due to join Liverpool in June, though they had explored bringing forward the deal in January.
And now, Leipzig have fired a dig at Liverpool, posting a celebratory tweet to herald the end of the January transfer window.
"It's February 1st!" the Tweet read, with a GIF of the 22-year-old dancing.
