Ok, you can think that. Sorry but not even close... Do we need Kaka? Answer is probably no. BUT...do we want kaka? Of course, what team doesn't?!!! And to say Sneijder is as good as Kaka is just ridiculous.
This is a ridiculous topic. Do you need a million dollars? Most people don't strictly need it, but everyone could certainly use it. If we are talking need as in imperious need, the answer is no. If we are talking need as in "could we use him?", the answer is who cares until the next transfer window. Therefore, thread closed.
