My own view, is that Froch should call time on his boxing career.
He's been a fantastic fighter and has fought some top class opponents but time waits for no man, and there's only so much punishment a body can take and at 36, improvement in any aspect of the sport is a big ask.
I would also guess that he was surprised last night at just how hard Groves pushed him.
He's notched up another victory, albeit one that's clearly controversial, and I think he'd be wise to take on board the opportunity to bow out of the ring and maybe take up any media, training or promoting opportunities, and spend more time with that gorgeous girlfriend of his and their young kids.
As I say Froch is a great fighter, right up there with the best British boxers, but maybe time to think hard about his future.
