Keita will join Liverpool at the end of the season in a deal which was agreed last summer worth £48 million.
The Guinea midfielder's performances all season have been exciting Liverpool supporters and Sunday's big game was no different.
Keita scored in a 2-1 victory against Bayern and also set up the other goal, assisting Timo Werner for the winner.
Keita was playing in an advanced attacking midfield role and the prospect of him adding to Liverpool's attacking riches next season is a scary one.
The Reds already have one of Europe's most fearsome attacks, led by the unstoppable Mohamed Salah.
Against Bayern, Keita created four chances and scored from his only shot at goal. Clearly one chance was all he needed.
Here is a look at how Liverpool fans reacted to his performance...
