Ukraine suffered a third-successive play-off defeat at the hands of Christian Ziege's Germany back in November.
Striker Sergei has teamed up with his national colleagues again for this weekend's LG Cup in Moscow but says he'll watch the World Cup 'on an island somewhere'.
"We've lost three times in play-offs," reflected the 27-year-old. "I don't think any other national team can say they've been in play-offs three times but not then been in the World Cup or European Championships.
"This time, when you lose, after the game you feel very diasappointed. You lose everything.
"But life goes on and you have to think about yourself and forget about the national team. You have to think about the future.
"Of course it is my dream to play in these finals but at the moment I don't think about the World Cup or European Championships. Of course I will when the time comes, but I have different things to think about."
He will be thinking about the LG Cup first and foremost.
Sergei explained: "It's a tournament in Moscow starting on May 17.
"We have two games. In the semi-final we play against Yugoslavia and Russia play Belarus. The final and the game for third place is then on May 19.
"I like to play for Ukraine. I like to be with the national team and, of course, for me it is very good to play for Ukraine. It is always good for me."
Sergei Rebrov admits he was heartbroken to miss out on a major tournament with Ukraine for the third time in a row.
