How would Barcelona pay for any of these players? They already extended Fati's and Pedri's contracts and we're talking about players that wouldn't be cheap. They could not get Wijnaldum on a free transfer 2 months ago, now we're talking about buying Sterling and bringing Messi back?
For Barcelona it would be better to keep a low profile and quickly kill off stories like these. Xavi will have a tough job by itself, with these kind of stories it will be an impossible one.
They cant without taking more loans the finances of Barcelona are probably the worst in the world. I do not expect them to sign anyone high profile for a long time. I think this season and next season they are going to lose a lot of players in the transfer windows. They cannot afford the players that currently play for them. Barcelona are not going to recover financially for a long time I think it will be 10+ years.
