Watching a bit of Man City playing 4-6-0 has made me believe Barca would absolutely destroy the PL bar Chelsea and City (would prob win it all), the lesser teams are terrible vs this style right now. They'd have to have a season to adapt like in Liga.
Its strange that City is so close to Chelsea now, and they even won PL last season. Yet they always look like shit in the CL, Chelsea always looks quite solid there.
