We'll see the development of negotiations between Barcelona and Bayern Munich. Indeed there are two possibilities for Lewandowski's situation, he will most likely move if Barcelona are willing to pay the amount of money Bayern want and if not then Lewandowski will finish his contract by requiring him to stay for one more season.
It might be good for Barcelona to wait for Lewandowski to be available on a free transfer at the end of next season, so it will definitely cost Bayern Munich.
I also think that the best decision for Barcelona is going to be to wait for 1 year and after that Robert Lewandowski is going to be a free agent. Barcelona will be able to get him for free instead of giving 50 million for this player. Trust me 50 million for a 34 year old player is not worth it. I just walk that Barcelona doesn't make any overall enthusiastic transfer as they did with Philippe Coutinho and suffer later.
Agree, 50 million is too expensive for a player who is already 33 years old, plus the financial crisis he is currently facing. Barcelona must prevent panic transfers, so far Barcelona have made many transfers that have made them suffer because players cannot show good performances like when they played at their old club. Philippe Coutinho
145 million euros, Antoine Griezmann
120 million euros, Andre Gomes
37 million euros, Arda Turan
34 million euros. They are a series of names that are included in the list of careless purchases that have been made by Barcelona.
Waiting for another year would be the best decision, Barcelona could get Lewandowski on a free transfer, moreover they can still rely on Aubameyang who has been performing well since his arrival in the January transfer window.
