The Reds playmaker will have a vital role to play in Liverpool’s pursuit of a place in the Europa League last 16 on Thursday night.
Firmino was unable to make the breakthrough in Germany last week as Jurgen Klopp’s side were forced to settle for a goalless draw in the first leg.
The Brazil international trained with his Liverpool team-mates at Melwood on Wednesday in front of the media ahead of Thursday’s game.
And Firmino popped down to a coffee shop on Merseyside to enjoy a well-earned break and a Snapchat session.
Firmino became Liverpool’s third most-expensive signing of all-time last summer after the 24-year-old playmaker completed a £29m move to the Reds from Bundesliga side Hoffenheim.
The South American has scored six goals and has made six assists in 23 Premier League appearances so far this season.
