Bar a luckless fall at Ascot IROKO has had an ideal campaign all geared around this race and he ticks most of the boxes, possessing the right blend of speed and stamina and seeming sure to stay back at a meeting where he has twice run well. He can give JP McManus a record-breaking fourth Grand National and third in 5 years. Perceval Legallois is another big player for the top owner, while Minella Cocooner could be the pick of the Willie Mullins' half-dozen. Intense Raffles is also in the mix.
