Yes, now trust in Nunez has turned into doubt. This is in line with the good performance of Haaland at Manchester City. I'm not trying to compare, but when these two players came to the Premier League it was a debate who was the best between them. Now Nunez is behind Haaland in terms of performance. Liverpool fans miss Sadio Mane.
Darwin nunez was brought on in the second half in the 62nd minute, during the match against Napoli, Liverpool's performance from the first half was very bad, so I don't think we can demand nunez to play perfectly in that match.
Unlike Haaland, Man City's performance in the domestic league is quite good and does not have many problems with the players. Haaland had a great start in the UCL tournament, not so good for nunez, in the second game in the premier league he got a red card. it's only natural that he's not at his best.
Liverpool's appearance in the UCL tournament was purely a failure of the main starter players, Moh Salah and colleagues played very badly.
