10. Gianluigi Donnarumma
This AC Milan goalkeeper is making headlines all over the world just at 16 years of age, making him the youngest goalkeeper in our countdown. For the same reason, many high profile clubs such as Chelsea, Arsenal, Manchester United and of course, Real Madrid are trying to sign this player. Rumours suggest that few of these clubs have even submitted bids of more than £30 million to sign this keeper, only to be rejected by Milan. Even the legendary goalkeeper Gianluigi Buffon has claimed that players like Donnarumma are very rare to find in the world. He comes at the 10th spot in our countdown.
