There have been a number of Italian soccer players that have worn the shirt number 8 both professionally and non professionally. There have been 6 soccer professional players with the number 8 on their shirt in the last year alone.
Lucas Neill is number 2
The number 10 is worn by the striker and usually the best player.
A player with the number 6 is usually a defensive midfilder. However, the number can be worn by any player.
The number 84 is not a particularly common shirt number. No player who is particularly famous has ever worn it.
If the team runs out of goalkeepers, they will have to send on a substitute outfield player to have a go. If they have ran out of substitutions, they have to send a player who is already on the pitch in. They have to put the keeper's shirt on, and his gloves.
