The Dutchman is combining his role as Russia's national coach with the Blues job until the summer and he rejected renewed speculation that he is to remain at Stamford Bridge for good.

Latest media reports claimed Hiddink would be replaced as Russia coach by Dick Advocaat but the interim Chelsea boss was unaware of any change to his situation.

"If there is something new I will announce it," said Hiddink. "There is nothing new. It is not an everyday issue and we stick to what we have said recently.

"I have settled in quickly. But I knew a bit of Premier League, English football and this club, and I am the kind of person who tries to adapt as soon as possible.

"This is high-level football and we have to keep up with the demands for this. I was very well received and have been backed up by all the departments assisting the first team.

"I am also very happy with the contribution of Ray Wilkins."

Hiddink also rejected claims that he had brought in tough new disciplinary measures.

The Chelsea players have begun wearing club suits to games and been fined if they are late for training. But the Dutchman said such discipline was normal for most clubs and not something he had introduced.

"So far I am very happy with the way we are working," added the Dutchman. "In my previous club, players were fined for being late for training and at the end of the season, we donated that money to a charity.

"It is standard to a club, especially a big club, that everyone is living up to a normal discipline. It is a normal discipline when you work at a big club and also a small club. It is nothing I have invented."

Hiddink's assessment of Chelsea after their 1-0 victory over Juventus was that they tired quickly in the second half. However, after studying data from their wins over Aston Villa and Juventus, the Dutchman has been forced into a re-think.

"We like to control the whole game," he added. "The first reaction is that the physical part is not at the required level. That is the easiest thing to look for. But I am backed up by data that this is not totally true.

"I have studied the last two games and when we have gone 1-0 up we have a tendency to drop back as a team and the gap between the defence, midfield and attack is too big.

"I have seen the figures and we ran more in the second half than in the first against Juve, but tactically we can improve and play a little bit more as a whole and reduce the spaces in between.

"That is more or less the conclusion I have made after these two games."

Hiddink, whose side face Wigan at Stamford Bridge tomorrow, was even more precise when it came to the question of the title run-in.

Chelsea are 10 points behind leaders Manchester United and - as well as hoping that Sir Alex Ferguson's side drop points - Hiddink conceded that to cash in on any slip-up, the Blues must win all their remaining league games.

"If we are focusing on the title then we have to win everything that is true," said Hiddink. "But Manchester United have to drop points as well and they are a very stable squad. It is difficult. But, yes, we have to win everything."

Hiddink has been boosted by the recovery of long-term injury victim Michael Essien.

Essien, out for six months with knee ligament damage, is to play against Aston Villa in the reserves next week.

"He is developing very well and working hard," said Hiddink. "He has a good attitude and an open guy.

"We worked with him in some tough five and eight-a-side games and we plan to play him in the reserves at Aston Villa on Monday."
