Sadio Mane will wear the No.10 shirt at Liverpool this season.
Mane previously wore No.19 at Anfield, but has now switched to the new number that has something of a chequered history at the club.
John Barnes, Michael Owen and Luis Garcia were all successful No.10s at Liverpool, but Joe Cole and Andriy Voronin fared less well.
If recent form is to suggest anything, though, Mane should enjoy the responsibility afforded by the number.
The Senegal international had an excellent campaign in 2017-18, scoring 20 goals in all competitions and providing nine assists. In the Champions League, Mane scored 10 times in just 11 appearances as the club reached the Champions League final against Real Madrid.
Mane captained Senegal at the 2018 World Cup, and scored in his side's 2-2 draw with Japan.
