Henderson wary of Yorkhill threat

Nicky Henderson has a couple of Willie Mullins inmates to worry about as the Cheltenham Festival approaches.

Yorkhill is now seemingly set to take on Henderson's reigning champion Buveur D'Air in the Champion Hurdle, while Douvan is creeping ever nearer towards a clash with Altior in the Queen Mother Champion Chase.

Henderson said: "Yorkhill is a very talented horse - hugely talented - and of course he is going to be a threat. Willie knows him backwards and all I know is that he is a very good horse and he will be a very potent danger.

"There will be lots out there and I take zero for granted. We've just got to concentrate on our own thing and Buveur D'Air came out of his gallop great.

"Altior worked this morning and he was very well. He was perfect. It was absolutely superb. He had his race the other day.

"That was his first gallop he has had since Newbury. He will do a bit at the weekend."
