The Gill Duffield-trained El Rigoletto will bid to defend his crown in the 1400m Group One Liwa Oasis, the highlight of Abu Dhabi's penultimate meeting of the season on Sunday.
The mount of Richard Hills, he will need to bounce back to his very best though having shown little in his four runs this season.
Saifaldin Deeb trains Dariya who looks certain to be a popular Pick Six selection after winning both his starts in the UAE after a long break.
He was a Group One winner in the UK in 2009 before injury delayed his local debut and jockey Ted Durcan said: "He is a very good horse and versatile with regards to trip and ground. Obviously he steps back up to Group One company but deservedly so and we have to be very hopeful."
He certainly would appear the class horse in the race with DAS Al Samer perhaps the one to chase him home.
It is also the Group Three concluding round of the Arabian Triple Crown over the marathon 2400m and only five go to post.
Hills will be in the saddle on the Musabah Al Muhairi-trained Tenor Des Vialettes who is penalised after his victory in the first two rounds, as well as the UAE Arabian Derby.
Frynchman re-opposes for Philippe Barbe and Kieren Fallon and looks a big danger, while stable companion Burkan Al Asayl looks best of the rest.
The only Thoroughbred race on the card is the concluding 1600m handicap in which the Dhruba Selvaratnam-trained Jaasoos returns to the course and distance of his Listed National Day Cup win in December.
He was then third in HH The President's Cup over 1400m before two runs at Meydan. He looks a nice spare ride for Kevin Shea who said: "He must have a good chance under his optimum conditions and I am looking forward to riding him and grateful for the opportunity."
Fallon's mount Dr Smart, trained by Al Muhairi, and stable companion Inestimable under Wayne Smith look big dangers, as do Doug Watson duo Marching Time and Prince Shaun.
With Iguaza Falls also a course and distance winner this season and Munaddam looking back near his best on his last Dubai International Racing Carnival run, it really does look wide open and a case could be made for all 16 runners.
