I think Barcelona won't be interested in him based on their financial problems. And in general, based on the financial problems of the Catalans we can say that for another 10 years they will have little interest in expensive players and stars. So there are two options left, either France or Saudi Arabia. Depends what he wants, money or continuation of a good career
Since Bernardo Silva contract ends in 2025, then Manchester City will definitely ask for money to sell him and this automatically turn down any hope for him to join broken Barcelona squad unless there was an exchange of players.
In the other hand Manchester City seemed not interested in selling the player. PSG for example, offered them an exchange of 3 players for him! These players are Marco Verratti, Presnel Kimpembe and Gianluigi Donnarumma! I could understand the first two wants to quit PSG but Donnarumma?
Manchester City have also rejected €70m offer for Bernardo Silva from PSG. Guardiola isn't ok for these deals apparently to avoid affecting much the team or Manchester City are expecting more money in order to let him go..
