Liverpool left-back Kostas Tsimikas named Alisson Becker as an "unbelievable player" after the Brazilian saved Jarrod Bowen's penalty during the win over West Ham.
The Reds took the lead in the first half thanks to a Darwin Nunez header, but Joe Gomez's foul gave Bowen the chance to equalise late on in the half, but Alisson had other ideas.
Tsimikas, who started in place of Andy Robertson on Wednesday night, believes Alisson showed what a "world class goalkeeper" he is with his performance.
