Montjeu looks to have Saturday's King George VI And Queen Elizabeth Diamond Stakes at Ascot at his mercy.
However, John Hammond's champion appears not to represent great value at his current odds of 8-11 to land the £750,000 contest.
He is undoubtedly an outstanding performer having won nine of his 11 starts including last season's Prix de l'Arc de Triomphe and the Tattersalls Gold Cup and the Grand Prix de Saint-Cloud on his two runs so far this term.
Montjeu was a breathtaking winner at Saint-Cloud.
He did not have to be at his best to record his fifth Group One victory but he did it in flawless fashion, defeating Daring Miss by five lengths with 1998 Arc winner Sagamix a length back in third.
Montjeu was reunited with Cash Asmussen for the first time since his success in last year's Irish Derby as Michael Kinane, who has ridden the colt since, was out of action with a back injury.
Asmussen was clearly impressed.
After the race he said: 'The last time I went so fast I was landing in a Concorde at New York - Montjeu has a great turn of foot.
'He is stronger and a more mature colt now.'
Montjeu has come out of the race well and is on course for the Ascot feature.
'Montjeu is fine - in good nick. Let's hope he stays that way between now and the race,' said Hammond.
Skinny price or not, Montjeu remains the one they all have to beat.
As expected the opposition includes several interesting contenders.
Godolphin, who have won the last three King Georges with Swain (twice) and Daylami last year, are set to rely on Gold Cup winner Kayf Tara and Fantastic Light.
Kayf Tara has twice won the stayers' crown but is not just an out-and-out galloper as he possesses a telling turn of foot, particularly off a good pace.
Any rain in the Ascot area would help his chances further.
One horse who does not want any cut in the ground is Fruits Of Love, a slightly-unlucky-in-running third 12 months ago.
The five-year-old, who has been plagued with injury problems, has only raced once this season, winning the Hardwicke Stakes - for the second year running - from stablemate Yavana's Pace at Royal Ascot.
Olivier Peslier will renew his partnership with the horse at Ascot as he attempts to improve on his effort against Daylami 12 months ago.
So long as he gets his favoured fast surface and Middleham trainer Mark Johnston can get him to post in one piece then Fruits Of Love is sure to be in the shake-up.
Johnny Murtagh has been handed the chance to land yet another of Europe's top mile-and-a-half races on Daliapour.
After his victory in the Irish Oaks on the Sir Michael Stoute-trained Petrushka, he has been given the mount on her stable-companion in the King George.
John Oxx's stable-jockey gets the call to replace the injured Kieren Fallon at Ascot as obvious alternative Pat Eddery is suspended.
Big-race wins have come thick and fast this year for the Irishman, who won the Vodafone Derby and Irish Derby on the Aga Khan's Sinndar.
If successful on Daliapour he would become the first rider to lift the two Derbys and the King George in the same year since Alan Munro won all three races on Generous in 1991.
'I'm thrilled to have got this ride and just have to pinch myself that things are going so well at the moment,' Murtagh said.
'Daliapour is a top-class colt who should go really well in the race.'
Daliapour has won the Ormonde Stakes at Chester and Vodafone Coronation Cup at Epsom to date this year to earn a quote of 6-1 with Coral for the King George.
However, improvement is needed if Daliapour is to trouble the principals at Ascot.
The main threat to Montjeu and possibly the best each-way value could lie with 16-1 chance Ramruma.
Henry Cecil's filly landed last year's Oaks, Irish Oaks and Yorkshire Oaks before finishing a gallant runner-up in the St Leger.
She reappeared in the Jockey Club Stakes at Newmarket in May when she came home a tailed-off last of 11 behind Blueprint after sustaining a muscle injury.
Ramruma has recently been showing signs of a return to form on the Newmarket gallops and on Wednesday moved well under Richard Quinn alongside the likes of Endorsement, Shiva and Beat Hollow.
Back to her best, Ramruma looks the one to give the favourite most to think about with Fruits Of Love set for minor honours once again.
