Roi takes on the big guns at Haydock Connections of Roi Du Mee admit the Gordon Elliott-trained eight-year-old faces a tough task when he lines up for the Betfair Chase at Haydock Park. The Gigginstown House Stud-owned chaser will be up against the likes of Cheltenham Gold Cup hero Bobs Worth, Silviniaco Conti, Cue Card and Dynaste in the big race over three miles and a furlong. However, he goes into the contest in good form having run out a shock winner of the JNwine.com Champion Chase at Down Royal last time, in which he beat Sizing Europe by 13 lengths. Eddie O'Leary, racing manager for the owners, admits it would be a surprise if he is good enough to get seriously competitive at this level. He said: "We've probably bitten off more than we can chew - it looks a fantastic race - but we're happy to let him take his chance. He won six races last season and he just keeps on surprising us. I hope he keeps on surprising us. "It was a step up for him at Down Royal and this is another big step up, so we'll see how he goes."
