Liverpool's goalkeeping coach John Achterberg has revealed how Alisson's fearlessness makes him stand out from the rest.
Since joining Liverpool in an eye-watering £65million deal in the summer of 2018 from Roma, Alisson has quickly emerged as arguably the best goalkeeper in the Premier League, if not the world.
Alisson won the Premier League Golden Glove and the Champions League during his first season at Anfield, and has played an instrumental role to put Liverpool on the brink of winning their first-ever Premier League title.
And Achterberg, who gets to work with the Brazilian day in day out, has explained just why Alisson is so formidable in between the posts.
