We're fighting to keep our heads above water with our CBs, but I think you stick with Kantari. I like Zavaleta, but a huge game like this for the kid? I feel like that's setting him up to be bullied by Drogba. Not that he can't bully Kantari either... sigh.
It's turned out to be a real shame Perquis had to pull his hamstring, he was on a decent run of form.
