London, England (CNN) -- Chelsea said on Tuesday that they had been given permission to talk with Guus Hiddink about taking charge at the Premier League club until the end of the season.
Guus Hiddink has the chance to take charge at Stamford Bridge until end of the season.
The Dutchman has emerged as the clear favorite to replace the sacked Luis Felipe Scolari, but his involvement with the Russian national team is a stumbling block.
A statement on Chelsea's official Web site www.chelseafc.com said they had been cleared to open negotiations with Hiddink.
"Chelsea can confirm that we have officially approached the Russian Football Union (RFU) to talk with Guus Hiddink to become the club's temporary coach until the end of the season while continuing to be in charge of the Russian national team.
"The permission has been granted and Chelsea would like thank the RFU for their co-operation."
Hiddink made it clear that he is in no hurry to commit himself to the Chelsea cause.
"I want to say officially that there has been absolutely no talk of me leaving the Russian national team," Hiddink told Sport Express. "I will stay and continue working with a team I feel very comfortable and at ease with."
Asked if he could combine both high-profile jobs, Hiddink replied: "You correctly use the word "if".
He added: "I can't rule out that option but it is at the stage of being examined. If everything is organised properly a move to London could happen. I'll be able to give you a final answer in a few days."
Hiddink, however appeared to rule out becoming Chelsea's new boss before Saturday's FA Cup fifth round tie at Watford.
"No, that's not likely to happen," he said. " I don't think things will be decided that quickly."
Hiddink has a strong track record in both club and international football and his agent Cees van Nieuwenhuizen told BBC Radio on Tuesday that he would be open to an offer from Chelsea owner Roman Abramovich.
"I think because of the personal relationship he has with Mr Abramovich he will definitely talk to him and listen to him but I think Mr Abramovich realizes he also he has not finished his job (with Russia)," he said.
"He is focused on his job with Russia, he is with the team on a training camp in Turkey and he is looking forward to qualifying with Russia for the World Cup."
Russia have two World Cup qualifiers between now and the end of the Premier League season -- Azerbaijan at home at the end of March and Liechtenstein away on April 1.
Hiddink has previous experience of managing a club and country at the same time, successfully combining roles at PSV Eindhoven and Australia.
Other names being linked with the job include former boss Avram Grant, ex-Barcelona coach Frank Rijkaard, AC Milan's Carlos Ancelotti, former Chelsea favorites Gianfranco Zola and Roberto Di Matteo and inevitably Mourinho, who is in charge at Inter Milan.
Scolari went on Monday after a string of indifferent results which have left Chelsea in fourth place in the Premier League, but in the last 16 of the Champions League and fifth round of the FA Cup.
"Unfortunately the results and performances of the team appeared to be deteriorating at a key time in the season," said a statement on the club's official Web site.
"In order to maintain a challenge for the trophies we are still competing for we felt the only option was to make the change now.
"The search for a new manager has already started and we hope to have someone in place as soon as possible.
"While that continues assistant coach Ray Wilkins will take charge of the team on a temporary basis."
The 60-year-old Scolari, who won the 2002 World Cup with Brazil before enjoying success with the Portugal national team, was the fourth manager of the Abramovich era, following Claudio Ranieri, Mourinho and Grant.
Ranieri, now Juventus coach, will take his side to Stamford Bridge for the first leg of their Champions League last 16 tie, a match that takes on added significance with Chelsea all but out of the running in the Premier League.
But Ranieri sees Scolari's sacking as a bad omen for his team.
"We could have done without this change," Ranieri told Press Association.
"Now the players will have an excuse and I, who had studied Scolari's team by memory, will have to start from the beginning.
"It will be another Chelsea and I will only have two weeks to get to know it."
