The Jean-Claude Rouget-trained Vadeni has now edged ahead of Charlie Appleby's Native Trail as favourite for the Group 1 race, while Bay Bridge is next in line at 5/1.
Bay Bridge failed to reel in State Of Rest at Ascot in the Prince of Wales's Stakes, ending his winning run of five, but he proved he was up to Group One standard.
Alenquer is set to represent William Haggas aiming to add to the Tattersalls Gold Cup he won last time out. Haggas could also run Dubai Honour.
John and Thady Gosden-trained Mishriff has won big races all over the globe but only one Group One in the UK could also feature along with Lord North, who struggled at Ascot when Frankie Dettori had trouble removing the hood in the stalls.
Aidan O'Brien has left in Saturday's impressive Group Three winner Aikhal while High Definition and Stone Age could also run for Ballydoyle.
Saeed bin Suroor has decided to go back up in trip with Real World - therefore avoiding recent nemesis Baaeed.
"He was second to Baaeed last time and is now rated 123, so we got the right race for him, even though he did not win," said Bin Suroor of his Lockinge and Queen Anne runner-up.
"We are on 194 Group One wins now and I would like to get to 200. We are six off that target and, realistically, Real World is my only Group One horse at the moment.
"He has taken us all around the world, so it is good. He has won Group Twos and it would be good to get at least one Group One with him."
