It was a difficult fight but I deserved to win it.

I'm more than happy with this. I worked 12 years for this moment. I'm used to booing. The crowd always cheers the short guy and I'm usually taller. I'm not thinking about being the first Russian heavyweight champion. I'm thinking about how to improve and win more titles.

I excuse myself as it wasn't the most beautiful performance. But I worked for 12 years for this moment. The most important thing is I won the decision and the championship.
