Kaka, why would he want to join chelsea?

I think it would be better for him to move on to another club, I mean c'mon, Real has too much players rite now in midfield, they have ozil and they also signed sahin. A player like him shouldn't stay in a club and just be benched. Besides I think Chelsea has a lot of room for a player like him, lampard is aging and so as the rest of the chelsea squad. They need a new life in their team so i think Kaka moving to chelsea isn't a bad move at all.
