Rival trainers John Moore and Tony Cruz are both predicting victory in the looming two-horse war between Viva Pataca and Hello Pretty at Sha Tin tomorrow. Viva Pataca, winner of the Hong Kong Derby and Champions & Chater Cup in the spring, has been hailed by two world-class jockeys - Christophe Soumillon and Michael Kinane - as the next big thing in local racing. However, according to Cruz, the rapidly emerging Hello Pretty has what it takes to lower the champion's colours in the HK$3 million Cathay Pacific Cup Trial over 2,000 metres. 'I think the key to this race is the five pounds between the horses. This is not set weights,' Cruz said yesterday. 'I think Hello Pretty has improved a lot since his first-up win in the Ladies Purse and I'm very confident of him running out a strong 2,000m. 'Viva Pataca will not only have to give him a start, he'll also have to give him weight, and I think that gives our horse the edge. 'I still have the utmost respect for Viva Pataca and whichever way it goes, this is a two-horse race.' Moore said Viva Pataca had 'improved in leaps and bounds' since his controversial first-up fifth to Green Treasure in the Sha Tin Mile Trophy, when jockey Eric Saint-Martin survived an adjourned stewards' inquiry into his handling of the gelding. 'I'm very confident I can win the race, but I will say the horse isn't quite at his peak,' Moore said. 'I want him peaking on December 10 for the Hong Kong Cup. But he's going to run a mighty race and I expect him to win. But put it this way, anything that does beat him [tomorrow] will be the winner.' Moore said he was eagerly looking forward to a 'golden era' when Hong Kong had several champions competing against each other in the big races. 'There is no doubt Viva Pataca is top class and it looks like David Ferraris has Vengeance Of Rain back in top shape again, so I predict these two horses are going to have some great battles as this season progresses. 'I have the utmost respect for Vengeance Of Rain - you cannot knock a world champion - but I think Viva Pataca has what it takes to serve it right up to him in these future battles.' Moore also reported a perfect bill of health for Viva Pataca. 'He's had a perfect campaign, absolutely no setbacks whatsoever - he's been a dream to train,' the trainer continued. 'He's matured even more, both physically and mentally. He's dropped a bit of body weight since his first-up run, so he's definitely fitter, and although he has been a bit fizzy at times he keeps improving in that regard too.'
