But he will be returned to the first team, with current incumbent Simon Mignolet rested, for the visit of the League Two side to Anfield on Sunday.
The 23-year-old even found himself the centre of a national debate after he was criticised by television pundits including Gary and Phil Neville and Jamie Carragher, a fact that irritated his manager.
“Whatever I could say is not good enough if the players don’t want it,” said Klopp of his team’s cup record. “These players want to have success, want to take every chance they get, and that has made it, up until now, really easy for me.
Liverpool manager Jürgen Klopp will recall German goalkeeper Loris Karius for his team’s FA Cup third round tie with Plymouth Argyle after praising his countryman for his response to losing his first team place.
Klopp led the Reds to last season’s League Cup Final, and defeat against Manchester City, before doing likewise in the Europa League, where his side was beaten by Sevilla.
“That is why you see I made the change and I am sure Loris will benefit from this step back, or step aside. Simon has done a really, really outstanding job for us since he’s been playing again and forced Loris to train at the highest level because we have two really good goalkeepers. It was good for him.”
