After what he said last night, about him wanting to be somewhere where he's loved, I think he's definitely going back to Chelsea.
Not good news for us, especially if he has financial backing this summer. I imagine that he would want a new striker, CM, and RB.
It will be interesting to see if he sticks with a Madrid style 4-2-3-1, or if he reverts to his tried and true Chelsea 4-3-3. I'd imagine he'll stick with 4-2-3-1 though, Chelsea's squad is built for it.
