I think the answer to 1) answers 2) and 3)

If comes back strong then i dont think he has any serious problem with either of those two champs, he's not too old - and i think he will only return if he is confident of being injury free - he will always be able to see how good he is compared to his brother, so will be well aware if he is a long way off his game.

That said a return against any of: sam peter; Mccline, povetkin, valuev or gomez would pose some form of stiff test; beating anyone of those would give us a strong indication he was back.

4) No, i think it was near perfect. Scaore cards show vitali slightly up - as he was. But his face was an absolute mess; he could have gone on but each round it would have been more and more difficult for him. It was stopped at the right time. Shame we didnt get the rematch though.
