German trainer Andreas Wohler reckons he has all bases covered in the Hong Kong Cup with his globetrotting star Silvano except, perhaps, for Japan. That is one country Silvano has never visited on his travels, which have netted him major victories in the United States, Singapore and Hong Kong this year, and Wohler believes Japanese challenger Agnes Digital presents a major threat. 'Japan has very good horses, as everyone saw in the Japan Cup,' said Wohler, whose dual Group One winner Paolini finished a disappointing 13th of 15 in last month's race as the home team filled the first four places. 'Agnes Digital has beaten T. M. Opera O, who was second in the Japan Cup, so he must be a top horse and I think he is the one to beat,' said Wohler, before adding that he was confident of beating two of the other main challengers. 'I think we will have the better of Jim And Tonic again and I'm not worried about Bach.' Silvano finished fifth in the Vase last year before returning to Sha Tin in April to land the Audemars Piguet Queen Elizabeth II Stakes over his best trip of 2,000 metres, beating Jim And Tonic by 1.75 lengths. And Wohler thinks his five-year-old son of Lomitas is ready to bow out on a high before he embarks on a stallion career at his owner's Gestut Fahrhof, one of the leading studs in his home country. 'He's looking very well and, although he's had a long season, I think he's in very good form,' Wohler said. 'His weight is good, he's moving well. It's a tough race, but it would be great to finish with a win.' Silvano had a routine half-speed gallop on the all-weather yesterday in preparation for his eighth start of 2001 in a campaign stretching back to his Singapore Cup win at the beginning of March. Since then, he has earned air mile points with trips to Dubai, Hong Kong, Singapore again, the United States and Australia. Along the way he has also won the Arlington Million in Chicago and never finished worse than fifth despite his gruelling schedule, though he ran in fourth behind Northerly in the Cox Plate. Press reports had attributed that defeat to a foot problem before the race and a bout of colic afterwards, but Wohler was not making too much of those excuses yesterday. Instead, he pointed to one of the biggest drawbacks all international equine competitors have to face - the quarantine issue. 'The quarantine period for Australia was longer than usual and Silvano had to wait in Hamburg for a long time,' he said. 'That meant I couldn't do as much as I wanted to with him and he was short of a gallop or two when he ran in the Cox Plate. That won't be a problem now, though.' On the problems in Australia, Wohler added: 'He had a slight touch of colic just after the Cox Plate, but fortunately it was nothing serious. He got over it very quickly. The foot problem happened about a week before the race but it was a pimple really and it only lasted for a day. He's been a great traveller all year and he should be perfect now.' Yesterday's workout was a poignant moment for Silvano's regular morning rider Bianca Sieling, who has been with Silvano every step of the way in his international campaign and was riding the horse for what will almost certainly be the last time. She will give way today to Silvano's race partner Andreas Suborics, who flew in yesterday for his big assignment, which will be followed by his debut three-month stint as a Club jockey. Silvano, whose QEII Cup win was the first in Hong Kong for a German-trained horse, will spearhead a three-pronged International challenge from the emerging racing nation, with Proudwings lining up in the Mile and Caitano back for the Vase, in which he was third last year. Proudwings is a hot fancy for the Mile, having arrived two weeks ago fresh from her success in Tokyo on Japan Cup day, and she was in keen form yesterday as she worked over a mile on the all-weather. The mare, a Group Two winner in England in July, is also due to retire after running on Sunday and trainer Ralf Suerland said: 'She's in good shape and it's good she's on her toes like that. That's how she is and that was a good piece of work. I am happy with her.' The Andreas Schutz-trained Caitano, who ran a disappointing 13th in the Melbourne Cup on his last start, worked steadily on the all-weather ahead of his latest bid for the Vase.
