The question is that.. will he go to M.City?
My prediction (since I try to foretell the future) is yes.. He will. This is an offer of a lifetime, and a chance to prove that he could make a team win. Note that currently M.City is actually at the bottom of the premier league.
If Kaka joins M.City and later on in the future makes M.City sit at the top three on the ladder, it will show that Kaka is a key player and very much an important factor of a winning team.
Staying at Milan may make him win trophies. But if your team is already a winning team, what fun would that make, and what proud would there be? (although Milan is not winning anything currently, and may not win anything this year)
So, Kaka, if you happen to understand english.. (hohoho) and read my blog… steady yourself, make the important decision, and move to City.
ps: I am a Chelsea fan, fyi.
