I love you Kun but I'd sell you for Ronaldo.
Kun is young, great and all that but it's Ronaldo who is absolute world star, more than Kun, one that make headlines and kids to become club fans, same kids that one day might be world star players and yearn to play for City, the club of their childhood so you don't get scared at each headline about your player wanted from his first love.
Kun can bring that too of course but on lower level and to be honest, I don't think he'll be at City at Ronaldo's age.
I find that thing absolutely most important thing in developing City as world's elite club. Until City comes to stage where 17-18 years players are ones who dreamed playing for City when they were kids, we're always going to shit ourselves when Barcelona or Madrid want our players and will lose many of them in signing process.
That thing is the edge Madrid, Barcelona and United mostly, and few other big clubs on smaller level have over City today and sooner that gap is closed sooner will everything be better and more stable.
And there's only Messi who can compete with Ronaldo as being main man for that goal as well as for short term results.
But this is all hypothetical and fantasy,, of course, so I hope City will do anything to keep Aguero, Silva and similar players. It would be disaster if we would fail to keep players of such big profile after 2-3 years. It would be very bad thing for club's reputation.
