Behind Barca and Bayern, above the likes of Inter and Union.
I was not only talking about other treble winning clubs though, but in the overall hierarchy
I doubt they'll be able to enter top 10 as of now, but with Pep at the helm for 2-3 more years they'll get there. It's just a matter of time.
But well, let them win the final first. It looks like a foregone conclusion right now, but maybe Inter will have a few tricks up their sleeve.
Just can't see them withstanding City's relentless intensity and pressing. Liverpool, Arsenal, Chelsea, Bayern and Real all got hammered so Inter shouldn't be any different. It's a final though, so anything happen.
