Guus Hiddink has once again ruled out the possibility of prolonging his time in the Chelsea hot-seat.
The Dutchman joined the Blues in February on a short-term contract which is set to run until the end of the season.
He agreed to combine his duties at Stamford Bridge with those in his role as manager of the Russia national side.
He has successfully adapted to the dual demands, keeping Chelsea on course for a multiple trophy haul and helping Russia edge closer to the 2010 World Cup.
However, he has made it clear that he has no intention of doing two jobs for an extended period of time and insists his international commitments remain his priority.
"It's important this relationship I have with the Russia players," said Hiddink.
"Because, even on a practical level, it's impossible to do. In August we have a friendly game which is 48 hours before a Chelsea game.
"Then you have to look at all the Russian players ahead of the qualifiers in September, and there are more qualifiers in October.
"Hopefully not in November, but there is a possibility of a play-off. So I'll be very occupied with all that.
"I know the body of the squad - so scouting isn't the main issue, but I've challenged them and it wouldn't be fair for me to leave.
"There is this project I started to renew with my people. It would not be fair with the players who I challenged to go into a new era of football if I said, 'sorry, I'm leaving'."
Hiddink is currently preparing his Chelsea side for a Premier League contest with Everton on Wednesday and insists the Blues are still capable of landing a treble this term.
"We have the attitude in the club, even in training sessions, that we want to win. So, what I try to say, is that tomorrow's game we want to win as well," he said.
"What's coming up at the end of May, at that time we will see. We still take these games seriously, even though we have the Champions League and the FA Cup coming up.
"The league is very serious for us. As long as it's possible for us, then we go on. The pressure is more on Liverpool than us in terms of Manchester United and the title.
"Mathematically it's possible. In February we had to make sure we qualified for next year's Champions League, but you cannot just be satisfied with that being such a big club.
"Everybody has done what is expected of him, so you push your targets higher. We are doing that. If you'd told us in February that we'd be playing in the FA Cup final on 30th May, people would have raised eyebrows."
Chelsea will be without midfielder Deco and right-back Jose Bosingwa for the clash with Everton as the Portuguese duo are both struggling with hamstring injuries.
