It was an insane team yeah, if talking about best team to ever touch a field yeah, that was one of them.
But club, i'd go for real madrid any day, they started building for the future for a year or 2 now, with vinicius, mendy, rodrygo, militao, odegaard, kubo, valverde etc..
Barca only has puig, fati & lenglet. Rest have no long future anymore at barca. So i'm afraid for them, as soon as Messi retires, players like pique, busquets, rakitic, suarez, griezmann will follow quickly, or even leave before he retires. Barca needs some good young players, and yet they keep buying players like pjanic, dembele (always something with that guy), coutinho ..
