We should be getting Paqueta ourselves maybe. Bernardo is approaching 30 and is pretty slow as it is. Not my preferred signing to be honest.
Bernardo is still 27 (soon to be 28) though, he can still give us 5 world class years, and until then Gavi will hopefully become truly world class and ready to be our starter week in week out alongside Pedri. Cause right now he's not, at least not yet. Bernardo is also another statement signing (that gives us one per every line) and an injection of world class into our team, just like Kounde in defense and Lewa in attack. Bernardo is perfect to take some pressure off our midfield teenagers for a few years. For under 100M (if the 80M rumours are true) he's a no brainer honestly.
We already got Kessie in the Paqueta age and quality range (good, and maybe even has potential for world class, but not there yet, and signed more as a differential to offer us something different). Bernardo is a sure thing, just like Lewa and (hopefully) Kounde.
As for Pedri and Gavi, we sometimes forget these are still 19 and 17-year olds we're talking about. Yes Pedri has thankfully already shown real quality to even be ready to start for us every week, but not Gavi (not for me at least). And a Bernardo-Pedri midfield link up (which is why Xavi wants Bernardo the most for) does sound pretty juicy.
