Guus Hiddink has indicated that he will leave Chelsea at the end of the season and return to managing the Russian national team full-time.

The Dutchman joined Chelsea less than two weeks ago on an interim basis following the sacking of Luiz Felipe Scolari and while continue trying to steer Russia to qualification for next year's World Cup.

It had, though, been suggested that he will take on the Chelsea job full-time in the summer and give up his international post, something Hiddink was keen to shy away from this morning.

"Chelsea asked me to help out till the end of the season and I have just done it because of the strong links between the Chelsea owner [Roman Abramovich] and the Russian federation," the 62-year-old said this morning. "I will help out to the end of the season. I have my work with Russia which I will fulfil."

Hiddink's priority now, though, is steering Chelsea's season back on course. The club remain in three competitions and the former Holland and South Korea manager believes they can secure all of them.

"Of course my role is a challenge but we are still in three competitions – Premier League, Champions League and FA Cup," he said. "We're 10 points down on Manchester United, which will be very difficult but we will give it a try. Things can change in a few minutes. I've made up that ground before in a different league. With PSV [Eindhoven], we were not that worried but there were some narrow escapes in the last few seasons.

"In the other two competitions Chelsea are still in the race. That's the challenge. I'm not just here to pass time until the end of the season. The players are used to winning trophies so let's try and repeat it. If they don't, you can't be happy."

Hiddink's first game is at Aston Villa tomorrow. Defeat would leave Chelsea five points behind Martin O'Neill's men in fourth place. "The priority is Villa Park," said Hiddink. "It's the cliche answer – the next game is the most important. If you see the record of Villa recently, they have very good period of winning games home and away. It's tough. But we want to play."
