B.) The argument for this would land better if Mane and Salah hadn't already just asked for more money than anyone else currently at LFC. What is to stop VVD, eventually Diaz, Trent and Allison doing the same in a yr or 2. If they did we would have let Salah and Mane go for potentially no good reason, if this was one the main reasons.
Sure new players may ask for parity with Mane's potential new LFC deal, but we generally sign younger players like Nunez/jota/diaz who are unlikely, we rarely go for Thiago types transfers.
Are you familar with the concept of the Overton window? If not look it up. The whole nature of wages, whether there is a wage structure in place or not, is that the highest wages given will move the wages Overton window upwards. Both intra- and inter- organisation.
Sure, giving Salah a gazillion pounds a week won't mean that Nunez and Carvalho and Ramsay will ask for parity upon signing; but it will mean that their agents will ask for more than they would have if the top wage at the club was lower.
The top wages have an effect upon all the other wages.
So I don't think these are the reasons we let Mane and might let Salah go. I think we may a tactical and squad morale based decision. Nunez was going to play and Firmino is more likely to accept being on the bench than Mane. For all the hype about a 5 great forwards last yr, Klopp had a clear preference for this 1st team forwards and their will be a clear preference next season, and it may not have included Mane, now that Nunez has joined
Er...no, we let Mane go because he wanted to leave. Maybe that was wage-related but maybe he just wanted a new challenge. We might well let Salah go for similar reasons. It's all probably rather simple and there's no point in inventing spurious reasons like 'squad morale' for what is in essence just the normal turnover of players.
It's weird (and this is a general commetn, not aimed at you) but in theory everyone accepts that players come and go and the squad make-up will change and turn over as the years pass. Everyone says they know that...until a player leaves and suddenly for some the 'natural turnover of players' doesn't apply anymore.
Players moving on is pretty normal
