Midday, placed in both the English and Irish Oaks, will try to land an elusive Group One success in the Blue Square Nassau Stakes at Goodwood on Saturday.The Henry Cecil-trained filly is among a field of 10 declared for the 10-furlong contest in which the Classic generation take on older horses of their own sex.Her best performance so far was when she was only beaten a head by Sariska at Epsom and High Heeled and Rainbow View, who were third and fourth that day, are again amongst the opposition. However High Heeled will only run if there is some rain.Sariska's trainer Michael Bell gives Moneycantbuymelove her chance at the highest level following her win in a Listed handicap at Royal Ascot. The other three-year-old in the line-up is Clive Brittain's Nashmiah.Owners Cheveley Park Stud are represented by last year's fourth Heaven Sent, as well as Spacious, while the in-form five-year-old Barshiba from David Elsworth's stable bids for a hat-trick after wins at Haydock and Newmarket.The John Oxx-trained Katiyra is the sole Irish challenger while William Muir's Saphira's Fire makes up the 10 contenders. Muir believes his charge will not be disgraced as she tackles Group One company for a second time after being unplaced in last year's Oaks.The Cape Cross filly had won her only two previous races before the Epsom Classic and is still relatively unexposed having had just five starts. She had been off the track since finishing third to Crystal Capella in a Group Two at Newmarket in October when fifth to Barshiba in the Lancashire Oaks at Haydock four weeks ago. "Martin (Dwyer) thought she was going to win but she got tired because she'd had a long time off," said the Hungerford trainer."He also said after riding work on her since that she's got so much speed we ought to drop her back in trip. This is the best option really though it's a hot race, a Group One. I'm not saying she can win a Group One, but I think she'll be very competitive."
