Derby and King George hero Adayar continues to attract support ahead of the Qatar Prix de l'Arc de Triomphe, with one firm predicting that he may soon usurp Tarnawa as favourite for Sunday's €5 million showpiece at Longchamp.
On Monday 14 horses were confirmed at what is the first forfeit stage, the opening act in a four-step process through the week, with both Adayar and Snowfall due to be supplemented at a cost of €120,000 on Wednesday.
Despite grey skies over Paris, the ground was officially described as good to soft at the start of Arc week following just three millimetres of rain from Sunday into Monday.
The penetrometer reading traditionally used by French track officials was 3.4 at 10am on Monday morning, while the TurfTrax GoingStick recently adopted measured 7.3 or good, good to soft in places.
The home straight and the descent into the false straight are currently good – as is the majority of the sprint track – while the back straight and the first part of the home turn are good to soft.
While there were more showers around on Monday, the outlook is mainly dry until Friday, beyond which there is little consensus among forecasters as to how much rainfall may arrive at the weekend.
With Snowfall waiting in the wings, Aidan O'Brien cut his original entry to two in the shape of Love and Broome, who are due to be ridden by Frankie Dettori and Yutaka Take.
Star fillies Tarnawa and Teona both feature, while one intriguing name left on the list at this stage is Derby and St Leger runner-up Mojo Star for Richard Hannon and Amo Racing.
Hurricane Lane, his conqueror at Doncaster, was confirmed on course for Longchamp by Charlie Appleby on Sunday and will be the mount of James Doyle, while William Buick will ride Derby and King George hero Adayar.
Four French-trained runners have been left in contention, with a decision due on Raabihah's participation within the next 24 hours, and similar deliberations going on in Prix Niel winner Bubble Gift's camp later this week.
Ladbrokes have kept Tarnawa as their 5-2 favourite but spokesperson Nicola McGeady reported that Adayar was now threatening the Dermot Weld-trained representative as market leader.
McGeady said: "Tarnawa is the worst result in the book but recently the majority of money has come for Adayar and we wouldn't be surprised to see the two switch places at the head of the betting."
