Chelsea chairman Bruce Buck has stated that interim head coach Guus Hiddink will definitely be leaving Stamford Bridge at the end of the season.
The Dutchman has impressed since joining the Blues following the shock exit of Luiz Felipe Scolari, but has always maintained that he will return to his main job with Russia's national team in the summer.
That line has been reiterated by Buck, who has confirmed that the search for a new permanent appointment is underway.
He told the club's official website: "Guus Hiddink came here on a temporary basis two months ago and it is thanks to the Russian FA that he was able to come here - it is purely a temporary role.
"There has been a lot of speculation about him staying, particularly as he has been doing a great job. That will not be the case.
"It is now up to the board to find a new manager for the long term and that is a process that we have started and that is ongoing.
"Anything you might read is just speculation at this stage. When we have an agreement for our new manager, we will announce it."
