Paul Nicholls is concerned that the Kempton track might not bring the best out of his impressive Charlie Hall Chase winner Silviniaco Conti.
The six-year-old was cut to as short as 5-1 joint second-favourite in places after he cruised to victory at Wetherby and it had been presumed the King George VI Chase on Boxing Day would be next on his agenda for which he is a 7-1 chance with Sky Bet.
Nicholls has claimed five of the six previous renewals with the recently-retired Kauto Star, but with Silviniaco Conti's stablemates Kauto Stone and Cristal Bonus putting their names in the frame with victories at Down Royal, the Ditcheat trainer has some thinking to do.
"He's (Silviniaco Conti) going to improve," Nicholls told At The Races.
"He ran really well last year around Kempton (second to Grands Crus in the Feltham), he is only six and I just want to mind what I do with him a little bit.
"He's done that nicely and we'll have a talk about it.
"One thing we saw was that he stays really strongly and I'm not convinced Kempton is totally the right track for him, so we'll just see and keep our options open.
"The three six-year-olds all won really well and we'll have to sit down and see where we go."
