A POSSIBILITY of heavy ground tomorrow looks increasingly like being the greatest fear for Frankel’s supporters with even Nathaniel’s jockey William Buick admitting he is attempting the impossible by trying to win the Qipco Champion Stakes.

Continuing rain at Ascot would certainly be welcome to connections of the secondfavourite Cirrus des Aigles, and Sir Henry Cecil and Tom Queally were not given the forecast they would have quite have wished for as Frankel takes a potential step into the unknown.

There is huge excitement ahead of what looks very likely to be the valedictory appearance of the world’s finest racehorse but there is a muddled look to the Berkshire weather.

Queally has been on board Frankel for each leg of his 13- race unbeaten streak, including nine Group Ones.

‘‘I don’t think soft would be a problem to him,’’ said the jockey. ‘‘It was quite testing on his debut and he handled conditions. Heavy ground might be a different story but if it’s testing, I can’t see it being any concern.

He went on: ‘‘He’s got to turn up as good as he has in the past and if he does, he should be very, very hard to beat.’’ Cecil did not attend a press conference in Newmarket yesterday but some quotes were circulated from the master trainer saying he ‘‘could not be happier’’ with Frankel.

But he issued some caution when he said: ‘‘I am pretty confident he will be fine in soft ground, but if it’s heavy we are in no man’s land.

‘‘He has never encountered it and, with his action and turn of foot, I cannot be sure that he would appreciate it.’’ Aside from his usual work companion and pacemaker Bullet Train, Frankel will face just four other rivals in the ten-furlong finale.

Last year’s winner Cirrus Des Aigles has proved a versatile customer while John Gosden’s Eclipse winner Nathaniel is another who likes to get his toe in and he remains the horse to have got closest to Frankel when beaten just half a length on their respective debuts at Newmarket in 2010.

Buick, though, seemed in little doubt he would be fighting for second place at best.

‘‘He (Frankel) has been fantastic for racing,’’ said Buick.

‘‘Tom and Henry have been great and he has been a joy to watch.

‘‘Obviously we’re all going out to beat him, but he’s unbeatable.

‘‘No-one can beat him, and I think on Saturday he’ll go out and do what he always does.

‘‘Deep down I hope he does, because if he goes out on a high it will be magnificent for racing. Obviously I’m there to try and beat him, but Frankie Dettori said to me last night, ‘get real, it’s not going to happen’.’’ One new rival for Frankel will be the German Derby winner Pastorius while Master Of Hounds will have his second run for William Haggas, having won in Turkey on his first start for his new trainer.

Aidan O’Brien will not be represented having taken out Declaration Of War while Prix de l’Opera winner Ridasiyna also bypasses the race.
