Bundesliga leaders Bayern Munich lost for the first time in 19 matches on Sunday as they suffered a 2-1 defeat away to sixth-placed RB Leipzig.
James Rodriguez's wonderful cross set up Sandro Wagner for the opener, but Liverpool-bound Naby Keita levelled the scores eight minutes from the interval with a close-range finish.
Back in August, the Guinea international agreed a deal to join Liverpool at the start of next season after the Anfield club triggered his £48 million clause.
Keita inspired Leipzig's comeback against Bayern with an impressive performance and it was his perfectly-weighted pass which released Timo Werner to score the winner.
As you can imagine, Liverpool supporters weren't shy to take to social media after Keita's top-class display - here's what they said about the incoming midfielder.
Keita stars in Bayern win
Leipzig have been inconsistent this season, and Bayern have a huge 17-point lead at the top, but that didn't stop Keita from producing a match-winning display.
The 23-year-old, playing in a slightly more advanced midfield role, registered a goal, an assist and came out on top in midfield battles with James, Arturo Vidal and Sebastian Rudy.
What Liverpool fans are saying on Twitter
After watching Keita dominate the best team in Germany, the general consensus amongst Liverpool fans on Twitter is that the all-action man can take Jurgen Klopp's side to the next level.
Reds supporters praised Keita's work-rate, some claimed he will become a Premier League star and others can't wait for him to link up with the likes of Mohamed Salah and Roberto Firmino.
Check out some of the best tweets below:
Keita, who returned to Leipzig's starting XI earlier this month after several weeks out injured, has provided five goals and four assists in 21 league outings so far this season.
While his disciplinary record has been questioned, it's clear that Liverpool have a very good player on their hands, and you can't blame their supporters for getting excited.
