Ah refreshing to confirm Toure is in fact a massive idiot who is comfortable with being somewhat successful instead of truly great.
Simple facts: defend a League title, win a Double and repeat that, win a Treble, win something in Europe while also winning your League (none of this Mickey Mouse Chelsea and Liverpool winning the CL while not being the best team in England), produce an era defining group of youngsters, be consistent in all competitions for the next 20 years (you're allowed an off year here or there).
If we are being picky then be more than just a modern day team, have some form of history Yaya ala Best and Charlton. Maybe even read history Yaya and understand our relatively low number of European wins has a pretty tragic explanation. Hell it might even have affected Madrid's own tally but we'll never know.
So just a few things for City to tick off the list and maybe then we'll talk but me and Yaya will most likely be dead before it becomes a real topic of conversation. If I'm around to see it become anywhere near a valid argument then I'll be truly impressed and I ain't even 30 yet.
