I'm already confused about the price of Lewandowski - they write that Barcelona offers 30, and Bavaria wants 40. The other day they write that Bayern wants 50 and Barcelona offers 40. But the most confusing is the position of Barcelona - on the one hand, they offer money, on the other hand, they seem to have no money and they offer to wait a couple of months until they find it

In my opinion, this is turning into some kind of farce.
It is true that Barcelona is in a financial crisis. However, the Barcelona management will do their best to take Lewandowski in the team. If necessary, they will want to take Lewandowski in the team even if he takes a loan.
Because Xavi's goal is to win the title next season, they definitely need a striker like Lewandowski. However, Barcelona may not be able to spend too much money now.
I would like to know where such ideas come from

Next year, Barcelona will fight for the top 4 (a ticket to the Champions League) and to qualify from the group in the Champions League to the next stage and, if possible, not be destroyed in the 1/8 finals. This is their maximum. By the way, the other day even Koeman said that Barcelona lives in the past and the Tiki-Taka strategy is outdated. But as you know, Xavi is not going to give it up.
However, this is the right moment for Barcelona to continue to offer prices to Bayern Munich, because Lewandowski himself wants to leave Bayern Munich because his salary is not increased. Therefore, with Lewandowski himself stating that he wants to play for Barcelona next season, then of course Barcelona will continue to do their best to recruit Lewandowski. With fresh funds that will be obtained from the transfer of Frenkie De Jong to Manchester United with cash funds of around 65 million Euros, then of course this value is sufficient to pay Bayern Munich the desired value of 50 million Euros.
