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.
