Why did Wayne Rooney change his kit number?
Well, the number 10 jersey was vacant for a whole year before Rooney took it. The number 8 jersey which he occupied is typically not used by attacking players like rooney; it is usually used by midfielders (mostly defensive). The number 10 is a number that is usually reserved for attacking players, strikers, or what the italians call the fantastista – the player in the hole behind the striker, like Francesco Totti – and this is what Rooney is.
