Almost impossible with Joan Laporta ambition for signing Bernando Silva from Manchester City, release from transfer market, Silva has values above 70 million euro and I don't think Barcelona have much money to pay transfer fees. Actually Barcelona still has debt for Manchester City last season after signing Ferran Torres with 50 million euro and right now they have paid 10 million euro only. Barcelona still facing with financial problem and how come have much fund for signing Bernando Silva, Manchester City won't to release fees transfer without paying full and they have realize how delay payment after signing Ferran Torres.
Realistic for Barcelona right now signing player with free agent, they don't have to pay payment fees transfer and Barcelona just negotiation with contract duration then how much salary will pay.
Barcelona's opportunity to get Bernando Silva is by exchanging players. it is rumored that Man City also wants Raphinha, and this could be another negotiation if Man City and Barca get an agreement. however, Raphinha is also a player that Xavi always chooses. of course, Xavi must really consider Man City's wishes. Barca are still having problems with their finances. I don't know how long they will get better.
Barcelona currently situation not allowing them to have any high price player because their debit is almost €1300 million which is more than worst and Bernardo Silva is almost €70 million which is not affordable for them even Manchester City board is trying their best for keeping this player, but he wants change with PSG is also trying their best but right now his future is uncertain at Manchester City.
As of now, Barcelona squad is strong enough and can do better which is surely good news for them, and they can go through without any big spending but still with this all they have no time frame about their problem's settlement because it's never been easy to reduce this debit hopefully something better will be happened for them.
