Florian Wirtz will wear the no.7 shirt at Liverpool next season, taking it from Luis Diaz.
Diaz has already been confirmed as a new Bayern Munich player this week.
Wirtz joined the Premier League champions in a 116million move from Bayer Leverkusen.
The No.7 shirt has been worn by several Liverpool legends over the years, including Luis Suarez, Kenny Dalglish and Steve McManaman.
Milos Kerkez has been given the No.6 shirt, while Jeremie Frimpong takes the No.30.
