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.
