JP McManus runs five horses in the Grand National as he aims to win the race for a third time.
Rachael Blackmore will once again partner Minella Times in the marathon contest after riding the gelding to victory in the race 12 months ago.
That gave McManus his second victory in the race after Don't Push It's success under AP McCoy in 2010.
On Minella Times' chances, BetVictor ambassador Blackmore said: "Minella Times was just exceptional last year. I got a great feel from him in the race. He jumped from fence to fence, and for me, it was very enjoyable. I’ll never forget crossing the line, so we’re out to try and repeat that.
"He’s carrying more weight this time, and although his form hasn’t been great this year, Henry found a couple of things amiss after his last run and has straightened them out.
"Since then, he’s been a lot better at home. Laura, who rides him out every day, is really happy, so it seems as if he is back to his old self.
"So, I’m really looking forward to it. This race is so full of history, and it would be great to add to that again."
Any Second Now, School Boy Hours, Anibale Fly and Enjoy D'allen will also run in his green and gold colours in today's race.
Any Second Now finished third in the race last year and looks to have another solid chance this time around for trainer Ted Walsh.
His daughter-in-law and former jockey Nina Carberry, speaking exclusively to Ladbrokes, said: "Any Second Now has a massive chance again this year.
"He has done very little wrong, he has won the Bobbyjo Chase, and he is running that distance again.
"He was completely hampered last year. I know he has a lot more weight which isn’t ideal but he is coming here with a brilliant run behind him and he has a massive chance.
"I think we deserve to be favourite, the weight might be putting people off a little bit but we know he acts around here and you need a horse who can jump at Aintree. He is a worthy favourite and one of Ireland’s leading contenders.
"Minella Times will probably show his best form all season here, and we know Snow Leopardess jumps around here as well.
"However, I think our biggest threat is Delta Work. He is another with a super bit of work under his belt coming here and I think he has the class. Everyone was saying he should have been in the Gold Cup. He may not have won it but he would’ve ran well and that’s the sort of class horse he is.
"If we can’t win it, I would love to see Ciaran Murphy win it with Enjoy D’Allen. It would be a lovely story for a small yard. He is in the race at the right weight and comes into the race in good form and has had a nice prep."
McManus only recently purchased Enjoy D’Allen and trainer Murphy is aiming to have his first ever winner in Britain.
The Noel Meade-trained and Sean Flanagan-ridden School Boy Hours won the Paddy Power Chase on his penultimate start and just got into the race on Friday as the third reserve after Easysland was the victim of an unsatisfactory scope.
And Anibale Fly runs in the race for a fourth time for Meath trainer Tony Martin. He finished fourth in 2018 and fifth in 2019, but was pulled up in last year's renewal.
