Interim Chelsea boss Guus Hiddink admits it will be difficult to leave the club this summer - but insists he will still return to his job with Russia.

Hiddink`s final home game in charge ended with a 2-0 win over Blackburn and a warm reception from the home support, but he is set to return to his Russian "adventure" following the FA Cup final, determined to honour in full the contract with the national federation.

However, the Dutchman - who took Holland, South Korea and most recently Australia to the latter stages of the World Cup - admitted it was only natural to wonder if he was making the right decision to leave Stamford Bridge.

"I have many second thoughts. Sometimes third thoughts. You cannot avoid them," he said. "You do not have a button to turn them off, but that is how it is.

"When I have to leave and I see the reaction of the players and how they have worked, I feel a kind of sadness. That is for sure, but that is the reality."

Hiddink added: "Russia is a country that needs to be developed. I have given my commitment to them, with pleasure, and I have to fulfil that - but that does not mean that it is difficult to leave this atmosphere."
