Because it was Lewandowski's wish for Barcelona and in the end they managed to play in LaLiga and compete with Real]
First of all, I don’t know how Barcelona is even being able to afford to pay this kind of money to Bayern Munich, and secondly, if this does actually end up happening, Barcelona is going to be a very strong team and a big competitor of Real Madrid in the next season in my opinion.
Obviously, I could be wrong, but Robert Lewandowski and the team will have a lot more stability, especially in the attacking department. And Barcelona better be able to win everything in the next season. Otherwise, they will have to repent about what they are doing right now.
Ideally, I didn't think they'd agree to pay the $50 million for Robert Lewandowski, which Bayern Munich wanted. And this is obviously overpriced, as is the case with Barcelona.
Barcelona have made good signings this summer despite the financial crisis they face in the club. Barcelona sold their tv rights and used the money to make these signings. I really commend their resilience in the transfer market and will be hoping to see good results as soon as possible because nobody will want to spend so much money on transfers and wouldn't want results in return. They have restructured a good team and with the kind of players on the team now they already seem to be league title contenders and one of the few favourites to win the champions league.
