They might as well wrap up the Premiership trophy and send it by special delivery to Stamford Bridge with a card attached: 'To be returned when Roman Abramovich takes up another hobby.'
That might be next year, in five years, in a decade, perhaps even longer.
As long as the Russian oil billionaire retains his interest in English football the rest can forget about winning the most prized domestic trophy.
We've suspected as much for some time but still it was chilling to hear Sir Alex Ferguson admitting as much after Manchester United's disappointing goalless draw against Arsenal at Highbury on Tuesday. "Chelsea's consistency is beyond us," he said. "We want to be the nearest team to them, just in case they have a Devon Loch moment and collapse."
With second-placed United 13 points adrift and Arsenal 24, Ferguson and Arsenal's Arsene Wenger know that is a horse not worth backing.
So the title race is over before the Christmas decorations have come down and the suspicion is that even Chelsea fans are becoming just a little bored with the ease of their dominance.
It would be wrong, however, to blame Abramovich entirely for the vacuum of competition at the pinnacle of the Premiership.
Yes, he has sanctioned spending on players which would settle a small country's national debt. Chelsea's consistency is facilitated by the size and quality of that squad which gives manager Jose Mourinho essentially two Premiership first teams to pick from.
While Mourinho has rotated his players shrewdly and built Chelsea's dominance on the meanest of defences the truth is that he has been ably assisted by the two clubs who set the standards for the Premiership throughout the 1990s.
The Premiership became the most exciting force in modern sport over a decade primarily because of the attacking philosophies of Ferguson and Wenger, allied to their driving ambition, feisty rivalry and canny ability to mould teams packed with power and adventure.
On Tuesday night at Highbury we witnessed just how seriously they had taken their eyes off the ball.
Ferguson's inability to replace Roy Keane, not just in the past six weeks but over the last three years, is his most obvious failing. The players he has bought or tried, Kleberson, DjembaDjemba, Smith, Fletcher et al, are well documented and none come close to the quality required. Roy Keanes, just like Patrick Vieiras, do not grow on trees.
Yet Arsenal's slide, in particular, is more than just about personnel. More, too, than a dip due to the distraction and demands of the new Ashburton Grove stadium they will move to next season.
Eighteen months ago Arsenal's so-called 'Invincibles' arguably were the most eyepleasing football team to grace the British Isles. Ambition was total, conviction unshakeable. These days Arsenal are without a captain and midfield inspiration. Wenger's insistence on packing his midfield against a side propelled by lightweight Darren Fletcher and John O'Shea highlighted the Frenchman's lack of trust in his side's ability to mix it physically with United.
