(Need to translate unless your Russian is up to par)
A couple key points:
"- Let's start with the most important. Is there a chance that you will not return to Russia and will start the season in the NHL?
- If that chance is, it is very minimal. I'll try to explain. Firstly, I have a valid contract with the Petersburg club and is unlikely to agree with the SKA its cancellation.
- You can redeem.
- Now it is not so simple. And whether or not I do that? Still ahead of the Olympics, and I have a great chance to play in this tournament. So I will spend the next season in the KHL.
- There are also some other reasons?
- Yes. For example, if I come to the NHL next season, then I get rookie contract, which all tied to bonuses.
If I come to the NHL after 28 years, I can sign a lucrative contract and choose the club. But this is speculation. In fact, I have decided nothing."
