Aidan O'Brien expects red-hot favourite Camelot to be joined by at least one stablemate in the Investec Derby field at Epsom next month.
The trainer, bidding for his first victory in the premier Classic since High Chaparral struck in 2002, having saddled 39 consecutive losers, said: "We are all very excited about the Derby, but it is a long time since we have won and many a year we have come home feeling very humble.
"Astrology won his trial well at Chester, but we feel that he will be even more effective on better ground, and he could be heading for Epsom, while, besides Ernest Hemingway, Sandown winner Imperial Monarch and Father Of Science, who broke his maiden at Chester last week, could also make the trip, though we will sit down with the boys before deciding on our final plans for the Derby."
