Next up is the Grade One Sporting Life Arkle Challenge Trophy Novices' Chase and we have nine runners going to post but it looks to be a two horse race between the two at the top of the market.
Although El Fabiolo has the best form heading into the race we are siding with the Nicky Henderson trained Jonbon who looks a much improved animal since going over fences this term.
A £570,000 purchase and full brother to the top class hurdler/chaser Douvan, Jonbon was an easy 15 length winner of his Irish PTP and subsequently went on to cosily land his sole bumper start on his first run for Nicky Henderson.
He then marked his debut over obstacles at Newbury, on the back of a 244 day break, with a cracking performance, winning by an eased down six length margin in November this year.
He stepped up in grade next time at Ascot in the Grade Two Kennel Gate Novices' Hurdle and again was an easy winner and then sent to Haydock on his prep run before the Cheltenham festival he was a determined winner of the Grade Two Supreme Trial.
His only defeat under rules came at the Cheltenham festival when second behind the superstar Constitution Hill, but he showed just how good he was on his final start of last term when landing the first Grade One of his career at Aintree in the Top Novices' Hurdle beating El Fabiolo.
Bought to be a chaser, Henderson gave him his debut over fences at Warwick on his seasonal debut this term and he looked an improved animal once more when bolting up at Warwick seeing off Grade One winner Monmiral and smart hurdler West Cork to win by seven lengths eased down.
Stepped up to Grade One company on his second chase start in December he again bolted up and landed the Henry VIII Novices' Chase from Boothill, who has since won and placed in decent Grade Twos.
Jonbon was last seen in his prep run for this event at Warwick when beating Calico in the Grade Two Novices' Kingmaker Chase.
He got a little scare that day when Calico went for home early but his jumping, speed and staying ability came to the fore and he was a comfy winner in the end.
Jonbon will have to put up a performance of a lifetime to land this but it is what his whole career has been about to date and we think his jumping compared to El Fabiolo might just be the difference.
