I understand that shirt #10 in soccer has historical significance. #10 is usually given to the best attacking playmaker on a team. The player that has good vision to make deadly passes and good ball control. My question is how did the #10 get assigned to this perception? Why not #9 or #7 etc..? I once heard that it has to do with an old formation and how shirt numbers were assigned. I believe in the old days they would assign squad numbers starting with 1 for the goalkeeper and then moving up through the defence, midfield, and forwards to assign the rest of the numbers up to 11. But what formation was used that placed the #10 shirt into a position that he played such an important role that the #10 wearer had to be a very gifted player if not the best player on the team? Thanks!
