#7 Alisson Becker - AS Roma
Not many know of Alisson's feats in 2017, but post the 2018 FIFA World Cup in Russia, the AS Roma goalkeeper could be a household name. This is a man who is keeping out the most expensive goalkeeper in the world for Brazil, and it may even be deserved.
Most Brazilians explain Alisson's #1 role for the Selecao as an outcome of manager's Tite's loyalty, but that does the former Internacional custodian a grave injustice. Becker took over from Szczesny for Roma and has not looked back, becoming a vital member of Eusebio di Francesco's preference for playing out from the back.
Alisson's penchant for pulling off one-on-one saves has bailed Roma out multiple times this season, and his numbers prove that he is a keeper who is improving at an exponential rate.
Keep it up, and a World Cup medal might be his soon enough.
