Nunez of course deserves another shot. Liverpool signed him for a really big amount of money. They can't give up on him after only one season. It is the truth that he hasn't been very impressive with his finishing skills since he joined Liverpool. He was amazing while he was playing for Benfica. It looks like he needs more time to reach that level.
Nunez is normally capable of competing with Haaland and Kane both for being the top scorer in a season. After Firmino's departure the expectation from him will be higher than before. He will have more chances to prove himself to the team as well. Hopefully we can see his real performance by the beginning of new season.
Jurgen Klopp, the manager of Liverpool, strengthened his midfield this summer by recruiting three wonderful midfielders capable of thrilling the entire midfield and important aids to the frontlines in terms of key passes. Darwin Nunez finds it difficult to adjust to Liverpool's football pattern, and the club has not performed up to expectations, being too hesitant and recording dismal results in league games. Competing against Erling Haaland, I don't think he can compete with the Norwegian international since Liverpool lacks what City possesses, which is a dominant midfield.
