Newcastle have completed the signing of former Liverpool goalkeeper Loris Karius on a deal until January.
Karius was a free agent after his Liverpool contract expired in the summer.
The German had not played for Liverpool since Alisson arrived in 2018, spending the last two years on loan at Besiktas and Union Berlin.
Newcastle head coach Eddie Howe told the club website: “We are pleased to add Loris to our goalkeeping group.
“He is a very good goalkeeper with Premier League and European experience and he will provide competition and support over an important part of the season.”
