Charles Byrnes believes Hurricane Fly is "the real deal" and is not confident that his Solwhit can beat Willie Mullins' star on Sunday.
Byrnes' star has been second to Mullins' runner on three out of his last four starts, however the experienced trainer says he has no option but to run the seven-year-old against his nemesis again.
"He's come out of his last race very well and he's in great form," said the County Limerick trainer.
"We are limited where we can go with him at this time of year so we've decided to let him take his chance.
"We're not expecting to beat Hurricane Fly, but we'd be very happy to come home second.
"From what I can see Hurricane Fly seems to be settling better in his races so obviously he's a lot stronger.
"He seems to be the real deal. One never knows if Hurricane Fly has an off-day. That's obviously the main reason why you have to take your chance."
Although Solwhit has been given an entry in the Champion Hurdle, he is likely to swerve Cheltenham and head to Liverpool for the Aintree Hurdle which he won in April 2009.
"It's probably more Aintree than Cheltenham at this stage," Byrnes went on.
"Naturally we have entered him in Cheltenham. It would be unfair to the horse not to make an entry for him there after all he's won for us."
