Cheltenham Festival Countdown video preview including the latest on Altior

Defi Du Seuil goes on trial for the Betway Queen Mother Champion Chase and is expected to get the better of star Irish veteran Un De Sceaux.

The pair consider Pentland Hills' return to action in The New One Unibet Hurdle and his position in the Unibet Champion Hurdle betting, while Matt highlights his latest Cheltenham Festival Antepost Angle selection and makes the argument for a 25/1 in the Arkle.

There are also reflections on the Sky Bet Moscow Flyer Novice Hurdle at Punchestown and a horse for the My Stable tracker that ran in the novice hurdle at the same meeting.
