Un De Sceaux, Vautour and Douvan have all been entered in Saturday's Bet365 Celebration Chase at Sandown by title-chasing trainer Willie Mullins.
The Closutton handler is locked in a thrilling battle for the British championship with Paul Nicholls, who also has three possibles at this stage.
Mullins' Champion Chase runner-up Un De Sceaux would appear to be the obvious contender, although Douvan has dominated the two-mile novice scene this term, winning the Arkle in fine style at Cheltenham before dominating his rivals at Aintree.
Vautour landed the Ryanair Chase at the Festival and he is also entered in the Oaksey Chase at Sandown.
Un De Sceaux finished behind comeback king Sprinter Sacre in the Champion Chase and Nicky Henderson's two-mile star is also in the reckoning for this race.
Nicholls has entered former champion Dodging Bullets, Grand Annual winner Solar Impulse and Ulck Du Lin.
Another Champion Chase winner in Sire De Grugy, the consistent Special Tiara and Kerry Lee's Top Gamble make up 10 entries.
