I'm not expert, not by far, but the first fight is the only time Iv been impressed by groves, I got as much of a fright as froch did at the way he went about it that night.. I think Carl looks a tad nervous as he knows what "might" be meeting him again at the weekend, personally I'm not sure if groves will produce another performance like that again, il take my hat off if he does. Picking a winner is as impossible as it gets.
