Reigning Grand National king Minella Times leads his stable's Aintree team.
The nine-year-old rose to the challenge 12 months ago, when he relished the fences at the Liverpool venue. Giving Rachael Blackmore a first win in the iconic marathon, it was a historic moment as a female rider had never previously scooped the big race trophy.
Minella Times is one of four intended runners for Henry de Bromhead on April 9. The trainer, who celebrated another major win with Blackmore in the Gold Cup several weeks ago, believes JP McManus' chaser is coming into form at the right time.
