History's littered with teams who played what is generally considered to be eye-pleasing football but didn't get the silverware they wanted ; 70's Netherlands, 90's Newcastle etc.
I think the problem nowadays is the social media generation have grown up with a team like Barca who for years not just played a certain way, but consistently won the trophies to go along with it as well, so I think more than ever there's this disgust at teams who don't try and sacrifice winning in the name of being 'entertaining'. Surely the beauty of the game is being able to appreciate different teams, styles, tactics etc. Brazil and Italy have both won a lot of World Cups and yet the stereotypical philosophies of both countries' football could barely be more polarised. It just shows that there's no right or wrong way to win.
