The 14:05 Dubai Challenge Stakes has an international feel with top German trainer Peter Schiergen set to run Amarillo (12/1) ridden by Martin Harley in the Group 2 race following June's Group 3 Jury Stakes victory at Haydock.
Sabrina Harty's Ansgar will look to cap off an incredible 12 months, in which the horse has progressed from being a handicapper to a Pattern class performer, coming second in the Group 3 Solonoway Stakes at The Curragh.
In total, 13 runners will compete in the 14:35 Vision.ae Middle Park Stakes, with Richard Fahey's Supplicant (15/2) a powerful prospect over six furlongs. He won his last three starts over that distance.
O'Brien's Great White Eagle (2/1) is the odds-on favourite; however, David Wachman's youngster, Sudirman (4/1), who has already won the Railway and Phoenix Stakes at the Curragh this year, is ready to challenge.
In total, O'Brien has engaged seven horses for the race against his rival Richard Hannon, who is running the durable Brown Sugar (16/1) and Shamshon (12/1). K.A. Ryan's Hot Streak (5/1), ridden by J.P. Spencer, is also fancied.
The Irish trainer will run with J.P. O'Brien on board War Command (11/10), who enters the race as the favourite. Hannon will try to compete with Anjaal (7/1), who makes the step up to seven furlongs for the first time. Sheikh Mohammed's Outstrip (7/4) will also feature.
Tiger Cliff, ridden by T.P. Queally will face stiff opposition, with Domination (6/1), Oriental Fox (10/1), Pallasator (10/1) and Smoky Hill (8/1) all capable of grabbing the win.
In the 16:25 - Vision.ae Rockfel Stakes, Olly Steven's Lightning Thunder (11/8), ridden by Harry Bentley, will fight it out with Marco Botti's Al Thakhira (9/2), Hannon's Lustrous (5/1) and Tim Easterby's Ventura Mist (10/1), with the first of the horses favoured for the win.
The 16:55 - Autumn Stakes features more horses trained by O'Brien and Hannon. Oklahoma City (5/2) will be ridden by J.P. O'Brien, and Pupil (12/1) will be ridden by R. Hughes, respectively.
Oklahoma City heads into the race as the favourite just ahead of Sir Jack Layden (4/1) and Safety Check (6/1).
Feuerblitz (7/1), French Navy (7/1) and Tullius (7/1) will be the key contenders besides O'Brien's colt.
