Aidan O’Brien unsaddled his Tipperary winner Granddukeoftuscany this evening and talked about the weather potentially affecting Australia’s participation in Saturday’s Irish Derby.

He said: “We all know he wants fast ground. There’s a lot of rain forecast for Saturday morning. A lot can change. We want to run him, but he doesn’t want soft ground.”

Australia is the odds on favourite for the blue riband contest. He was third in the English 2,000 Guineas on good to firm ground before impressively winning the Epsom Derby on good going.

The going is currently good to firm at the Curragh. Rain is forecast for tomorrow morning in addition to Saturday morning.
