Plus possible Nacarat swansong
Tom George says there is "every chance" Nacarat will be running the last race of his career as he aims to win a third Racing Plus Chase.
The Slad handler feels the valuable Grade Three handicap could be the perfect stage for the 12-year-old to sign off his racing days.
The grey has evoked memories of Desert Orchid with some superb jumping displays around Kempton, winning this race in 2009 and 12 months ago, as well as being placed the two years in between.
Although well beaten in the Old Roan Chase at Aintree and over the Grand National fences in the Grand Sefton this season, George hopes a return to his favourite track will turn around Nacarat's fortunes.
"He's in good old form, is working well and loves the track," said George.
"His work has been good at home and we'll see whether the fire is still burning back on the track this weekend.
"His two races this season haven't really been his thing and this race is the one we've really been aiming for since the start of the season.
"It might well be his last race. We won't shut the door completely but he can't keep going forever and owes nobody anything, so there is every chance it will be his last run.
"We know he loves Kempton and the ground should be fine.
"Saturday is going to a big day for him."
