Never been one to really pay attention to numbers, so most times, if a number is mentioned it will be a Liverpool player I come up with. When asked, goalies to me always wear 1, so I couldn't pick any that I associate with the number. For outfield players, the only top players that spring to mind when a number is said are
6 - Bobby Moore
7 - Dalglish
10 - Pele and Messi
13 Gerd Muller
Players like Cryuff, Beckenbauer, Jarzinho, Rivelino, Puskas, Best, etc, while great players, I have no idea what numbers they wore.
