Aidan O'Brien's Order Of St George is among 21 confirmations for the Gold Cup at Royal Ascot next Thursday.
The Ballydoyle stayer has been ante-post favourite ever since he turned the Irish St Leger into a rout last September, winning by 11 lengths. He reappeared with a win in the Saval Beg at Leopardstown recently.
Willie Mullins could pose the biggest threat in a showdown between the two dominant forces as he runs Melbourne Cup runner up Max Dynamite, who was only third on his return at Sandown.
The winner that day was Sir Mark Prescott's Pallasator and he remains in the mix, along with Luca Cumani's Mizzou.
Michael Bell's Big Orange will have supporters as will Clever Cookie after his Yorkshire Cup win.
Quest For More, Flying Officer, Curbyourenthusiasm and Scotland are other possibles to note.
