Simon Mignolet has at times stamped his authority on the No 1 jersey but is prone to errors and was dropped by Jurgen Klopp last month. Whilst Mignolet has at times not helped himself, it's always seemed Karius would be the pick if everything else was equal.
Mignolet's Liverpool contract lasts until 2020, and the 29 year old would be looking for a long term contract at another club, still feeling he has a lot to offer and also having a point to prove.
Clyne was included in Liverpool's 25-man squad for Wednesday's trip to Portugal, but Klopp admits the tie against Porto has come too soon for the England worldwide.
Salah, who joined Liverpool before the start of the season, is the league's second-highest goalscorer with 22 goals, one behind Tottenham Hotspur's Harry Kane and one ahead of Manchester City's Sergio Aguero while Firmino has notched 12 goals.
"For all goalkeepers it is the same, they need that [confidence]". "We had a little talk before the game, asking him what he thought " "No, I'm fine, boss".
"There were a few really good saves, important saves, good decisions - really smart decisions with quick restarts and stuff like that".
Karius has kept seven clean sheets in his 15 appearances so far this season, including three in the Champions League group stages.
