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.
If Barcelona management wants to do their best, they won't force themselves to buy Lewandowski. They have enough strikers, why do they need a new one? Lewandowski isn't a young striker, it isn't a wise decision to waste money by signing an old CF.
