Forpadydeplasterer and Sizing Europe are among the opposition to the history-seeking Kauto Star in the William Hill King George VI Chase at Kempton.
Paul Nicholls' brilliant chaser is bidding for an unprecedented fifth consecutive victory in the Festive highlight and will be partnered by Tony McCoy for the first time following the late withdrawal of Noel Fehily.
Nicholls is also represented by The Nightingale, while Nicky Henderson sends out a strong pair in Long Run and Riverside Theatre in the race that has been forced back by 24 hours due to the abandonment of Sunday's card.
Long Run won the Feltham Novices' Chase in brilliant style on this card 12 months ago, with Riverside Theatre unbeaten in four course starts. Nacarat, Albertas Run, Madison Du Berlais, Ollie Magern and Planet Of Sound complete the line-up.
Sizing Europe has filled the runner-up spot on his last couple of starts, chasing home Kauto Star in the JNwine.com Champion Chase at Down Royal last time.
Trainer Henry de Bromhead said: "He's been in very good form and we're very pleased with him. We hope he's improved since his last run but we are taking on a legend, so to finish in the first three or four would be a fantastic run.
"It's not a case of playing for places - you always want to win - but we are taking on a horse who is rated 20-odd pounds higher than us. Our run in Down Royal was better than that but he (Kauto Star) seems a different horse at Kempton.
"Sizing Europe has always looked a very good horse from the first day we galloped him and we're very lucky to have him, the way he has developed.
"The Champion Hurdle was a very disappointing day, but we've got him right again and haven't looked back since he's gone over fences."
