Trained by Nicky Henderson, Altior has won all of his nine starts over fences, a record which has seen him notch up 14 consecutive race wins.
Having triumphed in the (Grade 1) Queen Mother Champion Chase at Cheltenham, Altior signed off that campaign by registering a second successive victory in the (Grade 1) Celebration Chase at Sandown in April.
Despite his super-star status however, Saturday's (Grade 1) Tingle Creek Chase at Sandown is no easy task as he returns to action.
The Willie Mullins-trained 10-year-old has claimed nine victories at the top level, the latest of which came in the BoyleSports Champion Chase at Punchestown in April when he lowered the colours of his esteemed stablemate Douvan.
Harry Whittington's Saint Calvados likes to make the running and he is fresh from an all-the-way win in the (Grade 3) Poplar Square Chase at Naas four weeks ago, when reversing the Arkle Trophy Novices' Chase form with the well-supported Footpad.
The sponsors currently make Altior the 8-11 favourite with Un De Sceaux next best at 9-2. Sceau Royal is 5-1 and Saint Calvados the outsider of four at 6-1.
Betfair spokesman, Barry Orr, said: "Only the four runners but they are four of the five best two-mile chasers in training and the race is chock-a-block with quality.
"Altior has been favourite since the entry stage, that won't change between now and Saturday, but there has been plenty of support for the three remaining protagonists and a strong case can be made for each of them.
"It's a cracking renewal and looks a great betting heat."
