O'Brien keeps options open for Abbey Aidan O'Brien has described 2000 Guineas and Derby favourite St Nicholas Abbey as "unusual" as he prepares the colt for a Classic campaign. The son of Montjeu remained unbeaten through his two-year-old campaign and created a huge impression when waltzing away with the Racing Post Trophy at Doncaster. While O'Brien feels under no pressure to try and emulate Sea The Stars, who won both the Guineas and Derby last year, he does admit that St Nicholas Abbey appears to have all the attributes to become a star. "He's just ticking over and everything is fine with him, it is so far so good," said O'Brien. "He looked a very exciting horse indeed last year and we are very excited about this year with him, but at the moment he is just ticking over like them all. "I'm not sure where he'll start off yet, we'll wait until the spring when they all come together and see how they are. "They usually go away to work somewhere at the end of March and the Curragh are usually very kind and let us go there before the Guineas and we'll see where they all fit in. "All options are open to him at the moment. "Everyone saw last year that he looked a very unusual horse," he told At The Races. "He's by Montjeu, but he has loads of speed and obviously loads of class. He can cruise through his races and quicken. "He'll be trained with Classics in mind but he does look very unusual at the moment. "We are under no pressure to try and follow what Sea The Stars did last year, we'll let the horse tell us when he is ready to run and circumstances change every year, we'll just play it by ear and take one day at a time. "He'll be trained for the Classics though as they are what everybody dreams of."
