I agree with your assumption that Barcelona is the best team in the world right now, but Barcelona is the best team from La Liga. If you talk about the best team in Europe it is Manchester City and this season Barcelona is not one of them.
There is no better team in La Liga this season than Barcelona. The two titles they have won this season are proof that your assumptions about them are very weak, but of course only about domestic competition. I even really doubt how you came to that conclusion, I think you just don't want to admit it.
Actually, I don't want to compare these two clubs, but it's just that these two clubs have advantages and strengths in their respective standings, such as Barcelona being the best in LaLiga and Manchester City being the best in the premier league.
But for the best club in Europe, I feel that right now it's just Manchester city because it has managed to get 3 trophies this season and getting the treble title is enough to prove that Europe has the best club at the moment, namely Manchester city.
because man city has succeeded in getting the UCL trophy this season, they are the best in the world at the moment, but barceloan is on the right track and xavi just needs some more fresh strategies to be able to improve barcelona's performance in the ucl again, to compete in the local league, i see for the next few seasons barcelona looks like it will continue to dominate because madrid has not yet found a substitute for benzema and a good single striker.
