Sir Prancealot and Alhebayeb are both out to win back the TNT July Stakes for Richard Hannon at Newmarket on Thursday.
The trainer's stalwart Libranno lifted the six-furlong Group Two prize two years ago and the juvenile maestro would appear to hold a very strong hand.
"We have two solid chances," he said.
"Sir Prancealot was very impressive when overcoming traffic problems to win the National Stakes at Sandown, but the cards did not fall his way in the Coventry at Royal Ascot, though he still finished a creditable fourth.
"Our initial reaction was to drop back to five furlongs, but he won going away at Sandown, where there is a stiff uphill climb at the finish, so it is worth trying six again."
There are also hopes for Paul Hanagan's mount, and the trainer told www.richardhannonracing.co.uk: "Alhebayeb was doing all his best work at the end when runner-up in the Windsor Castle Stakes at Royal Ascot, so looks one who will definitely appreciate going up in trip.
"They are racing on fresh ground up the far side, so there should be no complaints about the going, especially on day one."
There is plenty of other Royal Ascot form around, with Aidan O'Brien sending over Norfolk Stakes runner-up Gale Force Ten for a rematch with David Barron's Ahern, who caught the eye in fifth.
Mick Channon's Chilworth Icon, a Group Three winner in Italy last time out, was fifth in the Chesham Stakes.
David Simcock gives Birdman a go in Group company after his ready wins in a Brighton maiden and a novice event on heavy ground at Chepstow.
"Birdman is an improving horse," Simcock told his website.
"He hasn't done a lot wrong so far and is ready for the step up in class."
Smoothtalkinrascal was another to compete in the Norfolk and an update on Brian Meehan's site said: "Easy Leicester winner (who) ran far better than his eighth place in the Norfolk Stakes might suggest.
"He was drawn on the far side, came across the course, finding trouble, yet was barely three lengths behind at the finish. The sixth furlong should suit, but this looks a strong renewal of this Group Two."
