No doubt about it. Charr won the first 2 rounds, arguably the 4th too. Vitali was running away again. Told you guys Charr's a great great fighter.
If Vitali got any balls, he will give Charr a rematch. Charr obviously didn't care about Klitschko's power, he just stopped bleeding and I think it's VERY unlikely that Klitschko would have knocked him out... IMO, the bloody stopage was very lucky for Klitschko. I don't know if he would lose, but he would certainly get his hands full.
