LEOPARDSTOWN CONFIDENT Prospects look bright for Sunday`s meeting at Leopardstown where Istabraq is set to bid for a fourth successive victory in the AIG Europe Champion Hurdle. The Dublin track was frost-free overnight and, although colder temperatures are forecast for the next two days, milder weather is expected over the weekend. Racecourse manager Tom Burke said today: 'We`re pretty confident at the moment. 'We didn`t have any frost last night and we would have been able to race today. 'The forecast is for frost tonight, for it to be cold tomorrow and for another frost on Friday night. 'The frost should gradually come out through Saturday and on Saturday night it is set to become milder when we should get some rain.'
