Nicky Henderson hopes Constitution Hill and Jonbon can put a dent in the Irish armoury in the Supreme Novices' Hurdle which kicks off the Cheltenhan Festival 2022 on Tuesday, March 15.

The elder statesman of British racing hasn't shied away from putting his top guns up against the best Irish talent and he will find stern resistance from Willie Mullins' Dysart Dynamo and Kilcruit.

Henderson's Constitution Hill and Jonbon are leading fancies to take supremacy but both are different characters.
"It was always the plan to run them both but they are like cheese and chalk," said Henderson.
"Jonbon will always be a bit flighty, it's probably a help he's in the first race and we'll have ways and means of hopefully keeping the lid on him because he'll be the one on his toes. We'll protect him from the atmosphere.
"Nothing will worry Constitution Hill, he's just so laid back. They will be two very good rides in the race. While Jonbon can be a bit keen in the race, there's no danger of that for Constitution Hill!
"Jonbon had a proper race at Haydock, but he quickened up twice in horrible ground which I was pleased with. By running Constitution Hill again, I was never going to find a competitive race. There wasn't anywhere else to go where you were going to get more than four or five runners (like in the Tolworth)."
Henderson compares both to his last two winners of the race, who went on to greater things.
"I think they are both very strong. Like Altior and Shishkin, you would like to think they are in their sort of league," he went on.
"It is always the best race to win on the whole card to be honest with you. We want to see England 1 Ireland 0. It is nice to have two, as two is better than one.
"They have done everything right and I hope all goes well. There is no doubt Willie's (Mullins) are good, but our job is to mind our own horses."
