Sergei Kapkov, the head of Russian billionaire Roman Abramovich's National Football Academy, which pays Hiddink's wages, said that the 62-year-old's contract "allows for the possibility of a joint posting and work by Guus Hiddink in any foreign or Russian club."
Hiddink has been strongly linked with the vacant Chelsea post since the London club sacked Brazilian manager Luiz Felipe Scolari on Monday after a run of what the club called "deteriorating" results. The club has been owned by Abramovich since 2003.
Media reports have suggested that Hiddink may take over as Chelsea manager until the end of the season. The Russian national side has just two World Cup qualifiers in that period - at home to Azerbaijan on March 28 and away to Lichtenstein on April 1, both of which should be easy wins.
The ex-Real Madrid and Dutch national team coach took the Russia post in 2006. Despite some initial resistance to having a foreigner in charge of the team, the vast majority of the country has now been won over. Indeed, such was the affection felt for Hiddink that babies were named in his honor after the side's 3-1 victory over the Netherlands in the quarterfinals of Euro 2008.
Hiddink's contract runs through the 2010 World Cup in South Africa, although he earlier said that had not ruled out extending it "if he felt needed."
