Liverpool boss Jurgen Klopp admits Loris Karius is now his senior goalkeeper.
Simon Mignolet, however, remains a key figure in the squad and Klopp is keen to have him involved as Tottenham visit Anfield in the EFL Cup fourth round on Tuesday.
Klopp said: "If nothing happens in training then he will play, 100 per cent.
"But in this moment we have a number one and that's Loris Karius. That's the situation and what the goalkeepers know. I cannot leave them in doubt.
"There was a short period with the two or three games we (initially) gave Loris to see a little bit more of him, but after the last international break I spoke to both of them and we made this decision.
"Of course, he (Mignolet) was not happy about this but nobody can see this in training. He is still working hard, improving, (doing) all that he has to do. He is a very serious person and a good professional."
