Not only Darwin Nunez but also Allison Becker saved the match, of course without Nunez's goals there would have been no victory but Allison's saves kept Liverpool in the game.
Nunez without salah was nothing. Salah has become a play maker for all of the goals scored by nunez. This is the main reason why liverpool never had an interest in selling him. Even when saudi was coming with a very big offer. Nunez knew where to put himself when all of newcastle defenders are still focusing on how to help to attack liverpool.
Not in vain Klopp so hoped for Nunez, even forced him to learn English, apparently to understand the seriousness of his intentions and here came Nunez's finest hour.
To be honest, I did not believe that Liverpool could win with ten men, but the left flank of the Newcastle defense fell apart and Nunez was able to score almost identical goals into the far corner from the left flank.
Me too, but this is football.
