I don't think that Lewandoski will go into Barcelona. Barcelona has a lot of issues with funds, his price is too high for a 33 years player, and also his fee is high. I don't think that Barcelona can afford him. But anyway, who
I am. My thought is always that he will end his season with Bayern and then he will be transfered to Barcelona.
From the gestures and words of Lewandowski some time ago it was clear he wanted to be at Barcelona and he even seemed to close himself off from other clubs like Chelsea and even some issues about Madrid.
And seeing that he has clearly said he wants to leave Bayern then I think what you said about ending another season at Bayern is a difficult one.
