What a weird comment to make. Aye, they are nowhere near the Guardiola team, but that was one of the best teams ever, of course that wasn't sustainable forever. They still lead La Liga by about a million points and have lost one competitive game all season IIRC.
They're doing well in the league, but there's no way this team wins the CL.
Be a different story if they can get Dembele and Coutinho properly integrated next season, maybe.
