Darwin Nunez was compared to Haaland. And while not scoring as many goals as Haaland, I think Darwin Nunez has the potential. He is not a worse player than Haaland. Since Liverpool's entire team was unstable. So we don't get a better performance than Darwin Nunez. If the Liverpool coach is able to stabilize the squad next season, we will probably see more goals from Darwin Nunez.
Sure, Darwin Nunez isn't a bad player. But he isn't comparable with Haaland. The number of goals means a lot, mate. It indicates how the performance of a player, especially since he is a striker (CF). You can see that the number of Nunez's goals in the last season is even not half of Haaland's total goals. Nunez's contribution to the field is also not as significant as Haaland's contribution. So, I'm not sure if Nunez has a chance to perform like Haaland in the next season. Although he is quite skillful but he doesn't have a good mentality as Haaland.
Nunez was predicted to play an important role in his squad after showing a very impressive performance at his old club, but in reality he had difficulty adapting to Liverpool which made him unable to show his best game. While Haaland didn't take long to adapt to Manchester City, he immediately became the new idol of the Etihad public due to his prowess in scoring goals. Haaland was more successful than Nunez in his first season in his at EPL career, he was able to bring Manchester to their first treble winner as well as being the top scorer in the EPL and UCL.
After going through a first season at Liverpool that was not too impressive, Nunez had to try hard to improve his performance like when he was defending Benfica. I can't say Nunez is a failed purchase for Liverpool because he has just finished one season with Liverpool.
