O'Leary explains what needs to happen for Tiger Roll to return to Aintree

Tiger Roll will aim to emulate the legendary Red Rum by bidding for a third Grand National only if the handicapper allots him a rating of 165 or lower, according to Gigginstown racing manager Eddie O'Leary.

Outlining plans for the dual Grand National hero, O'Leary said: "He won't run at the Cheltenham November meeting this year because it's a handicap.

"He'll have a run over hurdles before Christmas, then onto the Boyne Hurdle before running in the cross-country chase at Cheltenham. If they compress the weights for the Grand National, we'll run – but only if they condense the weights.
