This is a simple situation and it is the type of situation that can happen very regularly. Bayern Munich is not going to sell Robert Lewandowski for anything less than 50 million and obviously, Barcelona cannot afford 50 million right now. And even if there can be effort I don't think this player who is already 34 years old is worth anything close to 50 million.
So I don't think neither Barcelona should get this player nor Barcelona is going to be able to afford this player. I think for 15 million there are better players who are younger and will be able to give his service for a longer period of time to Barcelona. And honestly I really don't get it why Barcelona is still trying to make this deal happen.
I don't know exactly why Barcelona are still chasing and hoping big enough to get Lewandowski. maybe one side of Lewandowski performance that might be of concern to Xavi for him. But behind this signing, there must be big politics played by Barcelona, maybe by successfully getting Lewandowski, merchandise sales will increase quite significantly and can be an option for them to improve their finances.
before making a crazier bid for bayern munich i think barcelona management is still relying on manchester united in their interest in de jong, If this option fails maybe barcelona won't do much in the coming weeks to make a bigger bid on bayern munich.
the synchronization may be manchester united-barcelona-bayern munich maybe that's the pattern played by the barcelona management.
