McCoy's win in 2010 was a first in the race for both him and O'Neill
Trainer Jonjo O'Neill says Don't Push It can put up a strong defence of his crown in Saturday's Grand National.
The 2010 winner will carry top weight on Saturday and will again be ridden by champion jockey Tony McCoy.
O'Neill said: "There are a lot of good horses, some of them well handicapped but it depends if they take to it. At Aintree some do and some don't.
"A winner can fall at the first the following year. Don't Push It is in good form. We're very happy with him."
O'Neill's Welsh National winner Synchronised does not run in the race, but he could still saddle two other runners, Quolibet and Cant Buy Time.
He added: "Once you get a taste of it, you want to keep doing it. If he turns up in the same mood as he did last year, he'll give Tony (McCoy) a good ride and us all a good run."
