This is Nunez statistic, it's really crazy how he can perform when he playing for national team, but terrible when he playing for club. I guess that he's not comfortable playing in Liverpool despite Klopp have given many chance for him to play.
He's already two years with Liverpool, so I don't think he still need a time to adapt or improve, he should try to play on other team.
Nunez's performance with Uruguay in the last few matches has impressed everyone. Nunez's excellent performance helped Uruguay win by a big margin. At the same time, Uruguay's attack is now very strong.
Despite performing well with the Uruguay squad, Nunez is not performing as well as expected with the Liverpool squad. And I agree with you that Klopp is not using Nunez properly. Nunez scored 11 goals and assisted 8 with Liverpool last season. We cannot call this a very bad result. But if we compare with Haaland's performance then it can't be called a good performance. Liverpool fans expected more from a young talent like Nunez.
