Thanks to Marge
and BobbyG. Yes that is definitely Mishka Batanov, Ovi's childhood friend.
Here's excerpt from the article on http://teleweek.ru/35495:
"We are friends since we were 6 years old." - says Ovechkin's friend Mikhail Batanov. "We always see each other when he comes back. We loved to pull funny pranks and jokes.
We were about 8 years old when we started the fireworks on New Year's Eve by our apartment block. We had the fireworks that would explode in the air with a whistle. Sasha started his and accidentally hit the passer-by's butt when it exploded! An angry man rushed up to us shouting: "I'll show you, little bastards!" Sasha slipped into the building's entrance, but I was chased by that passer-by for a long time.
And once we found a bottle of beer in the Sasha's father car. We were incredibly thirsty! We quietly opened it and drinked. When Uncle Misha noticed, he slapped our butts. After that we never messed with beverages again."
