A clash between British champion Frankel and Australian superstar Black Caviar may still be unlikely, but Frankel's trainer Sir Henry Cecil says he is up for the challenge if the moment ever arrives.
Frankel is the highest-rated horse in the world ahead of Black Caviar with both horses yet to taste defeat.
Black Caviar, with 19 wins to her name, is being aimed at the Diamond Jubilee Stakes (1200m) at Royal Ascot in June. It would be her first appearance in the Northern Hemisphere.
Frankel is preparing for the European racing season and while Cecil said it would be lovely for the two to clash at some stage, he also said he would not alter plans with Frankel just to see it happen.
"Of course I would look forward to the challenge," Cecil told Sydney's Sky Sports Radio. "I think it would be fantastic but I must do the right thing for the horse.
