Hiddink has been a hit at Stamford Bridge since replacing Scolari as manager, but insists he will return to his role as manager of the Russia national side at the end of the season.
“It’s important this relationship I have with the Russia players,” said Hiddink.
“Because, even on a practical level, it’s impossible to do. In August we have a friendly game which is 48 hours before a Chelsea game.
“Then you have to look at all the Russian players ahead of the qualifiers in September, and there are more qualifiers in October.
“Hopefully not in November, but there is a possibility of a play-off. So I’ll be very occupied with all that.
“I know the body of the squad – so scouting isn’t the main issue, but I’ve challenged them and it wouldn’t be fair for me to leave.
“There is this project I started to renew with my people. It would not be fair with the players who I challenged to go into a new era of football if I said, ‘sorry, I’m leaving’.”
