De Bromhead said, "He was a 145 over hurdles and is now 3 from 4 over fences and a Garde 1 winner so you can't fault him.
"I'd say he will go for the Arkle now at Cheltenham. He's entitled to go now, and Roger loves to have runners at Cheltenham. It's been a great week for the Brookhouses.
"He fell at the second last in Cheltenham when going well so things have turned around our way today.
"It was disappointing that Identity Thief went at the first. He's generally a brilliant jumper and it was just a silly mistake. Hopefully we will get him back on track in the coming weeks."
Paddy Power and Betfair Sportsbook both quote Some Plan at 20/1 for the Racing Post Arkle at Cheltenham.
De Bromhead added, "We are leaning towards the Gold Cup with Champagne West but we would want a bit of ease in the ground for him. The handicapper has put him up 12lb to 166 so he is one of the top rated staying chasers in Ireland now."
