Grugy and Tiara among Kempton nine
Sir Valentino will attempt to bounce back to winning ways when he takes a drop in class in the 32Red Desert Orchid Chase at Kempton next Tuesday.
Sprinter Sacre and Sire De Grugy battle it out in the Desert Orchid Chase 12 months ago.
Having claimed the Haldon Gold Cup on his penultimate start, the Tom George-trained seven-year-old was only beaten just over five lengths when upped to Grade One company for the first time in the Tingle Creek at Sandown earlier this month.
George said: "He is a very tough horse and is in great form and he will now head to the Desert Orchid at Kempton. He will love the better ground."
Sir Valentino is one of nine entries that have been received for the Grade Two contest over two miles.
Nicky Henderson has entered Altior, who also holds an engagement in the Wayward Lad Novices' Chase on the same card, and Vaniteux.
The Seven Barrows handler won the race 12 months ago with Sprinter Sacre.
The Gary Moore-trained Sire De Grugy, runner up in last year's renewal, could bid to go one better and add to his 2013 victory, while the Henry de Bromhead-trained Special Tiara, winner of the race in 2014, is the sole Irish entry.
The list is completed by Garde La Victoire (Philip Hobbs), Marracudja (Paul Nicholls), Savello (Dan Skelton) and Ultragold (Colin Tizzard).
