Trainer Aidan O'Brien is responsible for the first four in the betting in Epsom's Investec Derby, to be run on Saturday 5th June, but it is still unclear as to which of his six entries will go to post.
St Nicholas Abbey, 2/1 favourite with Bet365, Ladbrokes and Paddy Power, and Derrinstown Stud Trial winner Midas Touch have both been confirmed on course for Epsom, but no decision has yet been made regarding Jan Vermeer and Cape Blanco.
Both colts looked serious Derby contenders after Jan Vermeer's smooth victory in last Sunday's Gallinule Stakes following Cape Blanco's impressive defeat of Sir Michael Stoute's Workforce in York's Dante Stakes.
The Prix du Jockey Club ( French Derby ) is run on Sunday 6th June and O'Brien is sure to be well represented, but only Irish 2000 Guineas third Viscount Nelson has so far been mentioned as a probable runner.
It is highly likely that either Jan Vermeer or Cape Blanco will join Viscount Nelson at Chantilly, and if the Investec Derby betting is any guide it looks as if Cape Blanco could be heading for France.
A strong second favouite after winning the Dante Cape Blanco has now drifted out to 10/1 for Epsom, whereas Jan Vermeer has been well supported over the last few days and is a solid 6/1 shot.
As Cape Blanco is out of a sprinting mare it would make sense to go for the Prix du Jockey Club, which is run over 1m 2f, as Epsom's 1m 4f trip is sure to favour the stamina laden Jan Vermeer.
O'Brien's other two Derby entries, At First Sight and Bright Horizon, are likely to play a pacemaking role at Epsom as their price of 100/1 + would indicate.
