Owner JP McManus says Shutthefrontdoor has been "laid out" for the Crabbie's Grand National all year.

McManus was speaking to RTE Radio One to promote 'Team Limerick Cleanup' in his hometown, and he was assisted by Tony McCoy and Ireland's successful Six Nations captain Paul O'Connell.

Shutthefrontdoor won the Irish Grand National for McManus and Jonjo O'Neill last season, only running once since, and has the honour of being McCoy's final ride in the race.

"Shutthefrontdoor and Cause Of Causes represent us in the Aintree Grand National and they both go there with good chances," said McManus, who provided McCoy with his sole National winner of the race in Don't Push It.

"Shutthefrontdoor will be ridden by AP in his last ever Grand National and he has been laid out for the race all year.

"He seems to be in good form and, with luck in running, he could give a good account of himself."

Meanwhile, Nick Scholfield confirmed he is expects to ride Spring Heeled at Aintree.

A Cheltenham Festival winner for Jim Culloty last season, he has been sparingly campaigned since then.

"It is not definite but it is likely that I will ride him in the Crabbies' Grand National next weekend," Scholfield told the Western Morning News.

"Looking through the betting, he is fourth favourite and it is a good spare to pick up.

"He goes to the race with an outstanding chance, having won the Kim Muir at the Festival in 2013, and he is under 11st in the weights, so he ticks all the right boxes.

"I was supposed to be on Sam Winner but he was not certain to run, and Paul Nicholls was very understanding when I spoke to him about this ride after I'd had the call from agent Dave Roberts.

"I have ridden in the race half a dozen times and my best finish was third on Teaforthree two years ago.

"The fences still take some jumping and it is the ultimate race to win. You grow up dreaming of riding in it and winning it."
