O´Brien Rues Valira Slip Michael O´Brien is likely to test the waters with De Valira next season to ascertain whether he has a potential Champion Hurdle candidate on his hands.Sent off at 9-2 in the vcbet.com Champion Novice Hurdle won by Clopf earlier in the week, the gelding crashed out at the fourth-last when travelling well within himself.'I think he was very unlucky,' O´Brien said.'He went into the hurdle half a length behind the other two and he landed on his knees, spreadeagled and hurt his back a little bit.'I think the the race was really run to suit him and I think he was very unlucky.'We´d have the Champion Hurdle in mind and it´s just whether he comes up good enough that is the question.'De Valira could finish only 10th behind Ebaziyan in the Supreme Novices´ Hurdle, but O´Brien believes that was not a true reflection of his ability.'When he went to Cheltenham he didn´t run too bad and our horses were wrong at the time. It really made a man of him and he was a different horse when he came back,' he told At The Races.'I was really looking forward to the other day because that was going to tell us what he was.'The five-year-old son of St Leger winner Shantou is a half-brother to the ill-fated Valiramix, who had to be put down after slipping up in the Champion Hurdle of 2002.(C) PA Sport
