Firmino has had a superb start to the season, and scored the 90th-minute victor against PSG, but Sturridge is pushing for a first Premier League start after resurgent form of his own, also scoring in the opening-day win over West Ham.
Firmino sustained an abrasion to the cornea in his left eye in the weekend win at Tottenham after a clash with Jan Vertonghen and did not train on Sunday or Monday.

Liverpool were rewarded for their excellent start as they found themselves two goals up after 36 minutes, Daniel Sturridge getting the opener before James Milner netted a penalty.
PSG did managed to halt Liverpool's momentum shortly before half-time when right-back Thomas Meunier reacted smartly to volley home a loose ball that popped up at the far post, and with his weaker foot too.

Despite his side's win over the French champions, in which Roberto Firmino bagged a stoppage-time victor, Klopp still thinks PSG are among the favourites for this season's Champions League.
"One, two or three years ago maybe people thought it's a mountain we can not climb. The squad is so strong as a unit", he said. We can't thank you all enough for your love and support. Obviously it's big for us to compete against teams like that. Keeper Alphonse Areola replaces the suspended Gigi Buffon but Tuchel will have to make a decision at full-back.
