IT is difficult to know how good Luxembourg is, or could be, and he is the correct favourite for the Vertem Futurity Trophy at Doncaster this afternoon.

Aidan O’Brien’s horse did well to win his maiden at Killarney on his racecourse debut in July, when he wasn’t that quickly away and, consequently, had to come wide into the home straight. He showed a really willing attitude, he kept on well under just a hands-and-heels ride from Michael Hussey to get home by over two lengths from Tuwaiq, with the pair of them nicely clear.
