Ahmed Musa, Harry Kane, Romelu Lukaku, Paco Alcacer, Paulo Dybala, Mauro Icardi and Ahmed Maghoub are the only players aged 23 or younger to reach double figures for goals in each of the past two seasons in Europe's top seven leagues.
Musa was the fifth highest scorer in Russia last season and has reached double figures in each of the past two seasons. That's a surprisingly rare sign of consistency for a 23-year-old forward. In fact, only six others of his age or younger have managed that feat in Europe's top seven leagues. Even at £16m that means Musa can be seen as a signing of substance rather than a gamble.
This is from a Sky Sports article when we signed him.
