A midfield duo of Bernardo and Pedri sounds class, but with the walking corpse behind them as the false DM, there are small chances it will work. To get the best out of those two in midfield we need a destroyer as a DM.
UEFA removed the CL stats which is annoying ( https://www.uefa.com/uefachampionsleague/clubs/players/250082664--rodri/statistics/qualifying/ ).
I would love to see the comparative data between Rodri and Busquets. I think we might all be quite surprised that Rodri is neither faster nor has more top speed than Busquets. If that is the case it will suggest that it is the overall system of Barcelona which is lacking and the whole personnel rather than Busquets in isolation.
The Spanish national team is a bit better unit than the Barcelona of late, and Busquets excels ahead of Rodri there.
Just a little nugget (hopefully someone can provide the data!)
