There were clear indications of Mane leaving Liverpool before the Champions League final took place and I don't think Liverpool want to reveal that because it could affect their performance in the final. It could be that things will change from Liverpool without Mane. Well, even though they have got Darwin Nunez but he still has to adapt to the Premier League atmosphere.
I think Liverpool are getting the players they deserve for Mane's departure, although Nunez will have to adapt first. But for a young player like him who has more motivation it looks like it will go well. When he plays well and as expected, I think Liverpool will easily move on from a Mane who we know he has contributed a lot to this club.
I hope Darwin Nunez hit the ground running when the league starts just like when Luiz Daiz came in January transfer window, though it will a difficult task to fill the impact of Mane after his departure from Liverpool, however I believe trio attacking force of Salah, Nunez and Luiz Daiz optionally with Firminho will be very strong and sharp, Nunez Nunez is a centre forward who can play also at the flank just like Mane, there is going to be a lot of expectations from him by Liverpool fans thus more pressure is on him to deliver, I hope Liverpool won't regret the exit of Mane to Bayern Munich.
