Let's give Burdisso a chance, and give Rivas a chance. Love what I see from Rivas so far, let's see if it is consistent. As far as Burdisso, he was great last year and before, so let's not look down too much on this rough year for him. Hope he bounces back!
I've never really rated Burdisso. He's never shown enough at Inter for that. I don't dislike him or anything but that's what I think of him. In the past he looked like he might be a half-decent, patch-up job replacement for our starting defenders, but he's really made me have severe doubts about this for more than a season.
I wasn't expecting much from Rivas...I didn't think he'd fare much better than Burdisso. But he has shown some good signs with good strong tackles and semi-decent composure on the ball (he really surprised me against Liverpool). He's also shown some signs of rash panic attack tackles though, which I'm not too happy about. But he's here to learn...and I think he deserves a chance to prove himself.
