Liverpool boss Jurgen Klopp says Loris Karius is the club's first-choice keeper but warned he needs to deliver.

Simon Mignolet began the season in goal for Liverpool but has not been named in the Reds' first XI since the club's New Year's Day win over Burnley.

"He's the number one now," said Klopp.

"Loris needs to deliver and he knows that."
