Karius new club
You're referring to Alisson Becker's brother, Karius!
Karius is a German professional footballer who plays as a goalkeeper for Turkish club Beşiktaş. He previously played for Liverpool FC from 2016 to 2018, but his time at the club was marked by a series of high-profile mistakes, including two costly errors in the 2018 Champions League final.
After leaving Liverpool, Karius joined Beşiktaş in 2018 and has since established himself as a regular starter for the Turkish club.
