Puissance De Lune boosts Glen Boss' confidence Deposed Melbourne Cup favourite Puissance De Lune appears ready to give next week's Cox Plate a shake after an impressive jump-out at Moonee Valley on Thursday. Race-day jockey Glen Boss was in the saddle and rated the workout better than that produced by Ocean Park before winning last year's weight-for-age championship. "I think he went better than Ocean Park did here last year, but he would have to because this year's race is a bit stronger," Boss said. Grey power: Glen Boss rides Puissance De Lune at trackwork at Moonee Valley on Thursday. Puissance De Lune has been building his spring since winning the Lawrence Stakes in August and has been runner-up in a pair of group 1s, the Makybe Diva and Turnbull stakes, at Flemington. He had a look at the Valley with a couple of stablemates from the Darren Weir yard and Boss could not have been happier with the way the grey rounded them up when he got serious from 600-metre mark. He is in a good space, I was happy with that. He's gone basically identical time to what Ocean Park did here last year, the difference being Ocean Park only ripped up half a mile, so he's gone real good, a lot better, but he's a better horse. I was very pleased with what he did between the 400m and 200m, that was very, very good because they quickened up, he gave them a start and went straight past them, so his sectional there was pretty dynamic. Boss was again asked if he was looking at other rides, especially considering the mount on Fiorente had become available in the Cox Plate after Damien Oliver was suspended at Caulfield on Wednesday. "I've never had any reservations about him," he said. The only reservations I've had is he's had his issues when the tracks are firm because he had an injury, which everyone knows about, but I've got no issues with this horse. If you asked me to swap any horse, there's absolutely no way I would swap this horse for any horse going into a Cox Plate, simple as that. It was the last piece of serious work for Puissance De Lune before the Cox Plate; Weir will take the six-year-old home for a couple of days by the beach. He'll probably have a trip to the sand dunes on Sunday, maybe a little bit of sharp work on Tuesday morning at the Warrnambool track. We'll just see how he is, but that's the plan at this stage. I think he's going to present in pretty good order on the right day. International raiders Side Glance and Mull Of Killough also had a look around the Valley. Craig Williams rode Side Glance in his work to get a feel before the Cox Plate but it didn't go to plan. "The saddle shifted, so I didn't really get any idea about him," Williams said. Fiorente went through his paces with Oliver in the saddle, while Manikato hopefuls Samaready, Rebel Dane and Sessions also had workouts on Thursday.
