Hiddink is in temporary charge at Stamford Bridge and, despite reports claiming otherwise, has continually stressed he intends to resume sole charge of Russia in the summer.
The Dutchman has impressed at the helm since taking over from Luiz Felipe Scolari in February, and has booked an FA Cup semi-final meeting with Arsenal and a UEFA Champions League quarter-final tie with Liverpool.
With Chelsea's Premier League title hopes fading of late, it seems the two cup competitions are their most realistic paths to glory this campaign - in what would be a memorable double.
But while Hiddink would savour such a feat, he insists the glory would make no difference to his allegiance to Russia.
Hiddink said in the Evening Standard: "It would be a beautiful scenario to win both cups.
"In that case I will not walk away from Stamford Bridge in my mind, but I will have to literally walk away because I have my full-hearted obligations in Russia and that is not going to change if we win those two cups.
"There is an emotional attachment with the Russian Federation and the people I work with - it would not be a good thing to leave them."
He added: "I look at the upcoming games this month and I'm excited. I won the European Cup in 1988 with PSV as a young manager, but it would be a dream fulfilled to win it again near the end of my career with Chelsea.
"Everyone knows that going to Anfield is like a hurricane. The atmosphere doesn't worry me, it excites me."
