Chacun Pour Soi is the favourite to win the Betfair Tingle Creek at Sandown on Saturday but Nube Negra is receiving support in the ante-post market.
Willie Mullins' market leader is 6/5 as he bids to add to his five-Grade One wins.
But there has been support for Nube Negra - 2/1 from 11/4 - who finished one length in front of the favourite when coming second in the Champion Chase back in March.
Last month, he impressed with a six-length victory in the Shloer Chase as he took his seasonal bow at Cheltenham.
That said, in his ante-post preview of the race, Betting.Betfair tipster Tony Calvin said he'd be looking for a bigger price if he were to back Nube Negra. Our man thinks it's worth keeping a close eye on Mullins' other entry Allaho 10/1.
Greaneteen, who was just a half-a-length behind Chacun Pour Soi in the Champion Chase is 7/2 from 5/1.
