Sire De Grugy faces seven rivals as he bids to end his spectacular season on a high by successful defending his crown in the bet365 Celebration Chase at Sandown on Saturday.
Gary Moore's champion chaser will be long odds-on to complete a five-timer in the hands of the trainer's son, Jamie, in a race which has this year been upgraded to Grade One status.
With Module and Somersby defecting, as anticipated, Sire De Grugy has over a stone in hand on official ratings, with Henry de Bromhead's Irish raider Special Tiara next in the list.
Nicky Henderson saddles French Opera on the day he relinquishes his champion trainers' crown to Paul Nicholls, with the Ditcheat handler represented by the out-of-form Kauto Stone.
Claret Cloak, Lancetto, Pepite Rose and Australia Day complete the field, although trainer Paul Webber said the latter will only run if the ground is suitable.
