Should Firmino miss out on tomorrow's Champions League clash then it will come as a significant blow to Liverpool as the Brazilian makes up one of the main focal points in Jurgen Klopp's high-octane attacking trident.
"When I saw a few games at the World Cup I know people were talking about that when it looked like he made more of a situation than it was, " Klopp said on Monday, a day ahead of the Champions League match (NZT Wednesday).
We have built our squad so we are able to compete and now is the time for all players at Liverpool to embrace the best two club competitions in the world. He is quick to play down that record, however, pointing out that Tuchel was not in charge of a side containing the likes of Neymar and Kylian Mbappe before.
Liverpool will be confident of their chances of beating the French champions though, having reached last season's final.
A role he should have no worries about undertaking, Salah could switch from the flank and it could see Xherdan Shaqiri handed his first start of the season, as he can join Sadio Mane on the wings with that duo providing Salah with the service, and Mane and Salah can interchange with each other to upset the PSG defensive line.
"We play football and we want to win the ball, we don't try to act in these kind of things; we try to avoid passes to him, try to avoid him winning challenges - which is a big job to do. In which role, I can not tell you because it would make things very easy for Liverpool to prepare", he replied. "Another 30 hours until the game so we will see how it develops". If he will be fine for tomorrow, I don't know in the moment. But he enjoyed the greater success at Mainz, leading them into Europe in 2011.
"He always gets kicked a lot so he needs to try and use it as best as he can".
Instead he chose to partly excuse Neymar's actions in the face of physical treatment from defenders - something Klopp says Liverpool will not be participating in on Tuesday. "In all the games, we have had some really good moments, but today we had 85 brilliant minutes".
"We don't go for him against us". You think with Man City winning it previous year, and the squad they have got, it is going to be a tall order. But for us we just need to treat it as a normal game, a big game for us, which we've proved against big teams before that we can perform and that we can get the result we need.
