AIDAN O'BRIEN'S weather concerns don't just centre on Dublin, as he is also hoping for fine conditions over Paris to allow Henrythenavigator run in tomorrow's Group One Prix Du Moulin at Longchamp, reports Brian O'Connor.

The dual-Guineas winner is due to face star fillies such as Natagora and Goldikova in the mile highlight, but testing ground could yet scupper Ballydoyle's French raid.

"It's soft there now but they are hoping for a couple of dry days," O'Brien said yesterday. O'Brien's focus at Dundalk tomorrow will be another attempt to get a win into Great Barrier Reef in the mile maiden, but for punters Dark Humour looks a much better option in the two-year-old maiden. Dermot Weld's runner ran into a good one in Sea The Stars at Leopardstown and a repeat of that form should be more than enough.

Wayne Lordan's choice of Miss Puss juvenile conditions race looks significant.
