These are not rumors, but the official position of Bavaria (another thing is that at some point in time they may agree to a smaller amount than requested). But I have a suspicion that due to Lewandowski's behavior, this issue has become a matter of principle. In this case, he will either have to play for a year or sit on the bench. As for the expectations of Barcelona, it is not known what form he will be in a year (although if the crisis in Barcelona continues, it is possible that it will be happy even the old Lewandowski 
).
).Lewandowski will stay with the Bayern Munich team and he will try to maintain his form. Lewandowski is a professional player, he will not intentionally play badly. And if Lewandowski is with the Bayern Munich squad, he will be the key player in the squad. But I wanted to see Lewandowski in Barcelona. However, this possibility seems very low. A few years later, I don't think Barcelona would be interested in a 34/35 year old player.
As far as I understand Bayern's first training session after the break will be on July 12 and this is the first date we will see the continuation of this scandal (whether Lewandowski arrives or not). I already wrote earlier that at the moment Lewandowski lost the war he started and now all the trump cards are in the hands of Bavaria - what this will lead to is not yet clear. As for Barcelona, so far I see a lot of chaos in them, words, etc. but there are very few real cases.
But if the transfer would took long time to complete .. i think he could just join the first bayern training session and act like nothing happened but waiting.
Lewandowski transfer saga are indeed worth to wait.
