Chelsea's influential director of football stunned club bosses when, soon after Ray Wilkins' dismissal as assistant-manager, he announced he would leave when his contract expired at the end of the season.
Shock decision: Frank Arnesen
The shock development, exclusively revealed in Sportsmail a week ago, led to speculation that the 54-year old Dane had sensed an uncertain future and decided to walk before being forced out.
But, while he may have been unsure of his position, Sportsmail has learned that his main motivation was to alert Denmark Federation chiefs of his availability for a post about to be vacated by long-serving coach Morten Olsen.
Appointed 10 years ago, Olsen (61) has officially confirmed that he will stand down as Denmark manager in June, 2012 but intimated to friends that he may bring forward his retirement by 12 months.
That would coincide with Arnesen's departure from Chelsea, and the former Tottenham director of football spelled out his ambitions when he addressed a meeting of around 150 businessmen in Denmark recently.
'To be coach of your own national team would be very special,' he said. 'I cannot think of a higher honour.'
Arnesen's pitch for the Denmark job would appear to rule him out of another Abramovich link-up, this time with Chelsea owner Roman's son Arkady at FC Copenhagen.
Attractive option: FC Copenhagen are currently top the Danish League
Abramovich jnr appears to be on the verge of following his father into football club ownership after having lunch last Saturday with one of FC Copenhagen's main backers, in what is being viewed as an opening gambit in a likely takeover bid.
He met Carsten Koch, chief executive of Loenmodtagernes Dyrtidsfond, at the city's Cafe Victor to discuss the pension fiund's 30 per cent stake in Denmark's leading club.
'Right now, we are not really sales-oriented,' Koch said, before adding that 'should someone come with the right price, it could well be.'
Any suggestion that Abramovich snr may be trying to add the Danish champions to his purchase of Chelsea in 2003 was ruled out by Federation president Allan Hansen, who said: 'We are aware of the interest in FC Copenhagen by Arkady Abramovich. It would not be possible for his father to be involved in a takeover, because any individual is only allowed to own one club.'
A buy-out of Loenmodtagernes Dyrtidsfond's shares would give Arkady a majority holding in FC Copenhagen, who currently top the Danish League and could become the first team from their country to reach the knock-out stages of the Champions' League, as they approach Tuesday's game against Panathinaikos in second place in Group D.
Wealthy businessmen Karl Sorensen and Erik Skjaerbaek own around 15 per cent each, with the rest of the shares scattered among small investors.
But any thoughts of installing Arnesen as manager could be scuppered, if Olsen decides to step down next summer.
