Hiddink does not feel he has time to continue at Chelsea while working to orchestrate Russia’2 2010 World Cup campaign.
He told The Sun: “I have a formal contract with Russia and it is very important for me to stick by my word. The moral standards in our business sometimes go up and down but I want to see my commitments wholeheartedly through to the end.
“I owe something to the Russia players. If I were to end a contract which had not yet expired, they could blame me for not standing by my own values.”
He added: “I could help as Chelsea boss this season because Russia only had two games.
“But next season Russia has a friendly in August and a very tough sequence of qualifying matches in September and October.
“Then there is also the chance they will be involved in the play-offs so the situation becomes impossible.”
