#2 Alisson Becker (Brazil)
It's not as if Alisson Becker needs to prove his abilities as a guardian of the posts. The AS Roma shot-stopper gained worldwide attention when he played the most crucial role in Barcelona's quarter-final exit in the Champions League this season.
The World Cup is just another chance for the 26-year-old to remind the clubs of his powers as a goalkeeper. He already has two clean sheets under his belt and is a strong contender for the Golden Glove in Russia.
Alisson has no shortage of worthy suitors, with Liverpool, Real Madrid and Chelsea all waiting in line for his signature. However, should he continue his form on the international stage, he will definitely go for a fee bigger than the rumoured price tag of €70 million.
