We will see if Liverpool really made a mistake by selling Sadio Mane. It is still early to make such predictions about the situation. As I said before, it is depending on how the new trio will play and how Darwin Nunez especially will play in this season. Liverpool got really close to a championship in the league last season but lost their chance by inches. They need to put a bigger effort into it this time to be able to get ahead of Manchester City. They will need to decrease the amount of points lost in easier games to make a difference.
Just 2 or 3 games and fans are already tearing Nunez apart for his poor performance and lack of goals in the pre season matches. I think he should be given more time to adapt in the team, hopefully he will blend in and the team will play even better and be able to match the league champions and rivals Manchester City. I think by now they are done with transfers this summer and will now focus on building the team to play together.
And today everything looks different than before. Nunez impressed against Leipzig and he started scoring goals so many people will probably change their point of view of him. If previously he was judged badly, it was only because he had not adapted to the game and strategy in his new team, that's only natural. But now things are going well for him and Liverpool, but obviously it's pre-season.
Indeed, sometimes the price does not guarantee quality, but about Nunez he can become a new star in the Premier League. I'm curious about Haaland if he can impress at Manchester City during pre-season and when the season starts, and I'll be looking forward to his performances too.
