Daryz, Gstaad, Opera Ballo and Benvenuto Cellini all line up on an outstanding Arc Trials Day from Paris Longchamp on Sunday.

Daryz returns to Paris Longchamp en route to his defence of Europe's most prestigious race, tackling the Prix Foy. Francis-Henri Graffard's star returns having not being seen since his third in the Prince Of Wales's Stakes, where there were excuses for the run given his misbehaviour in the stables prior to the race. That run is the only blemish to an otherwise seamless four-year-old campaign to date, which has seen him win the Prix Ganay & Prix Aga Khan IV, showing a devastating turn of foot in both.

Gstaad reopposes two of his rivals from the Sussex Stakes in Sunday's feature Qatar Prix du Moulin de Longchamp for a pot just shy of £400,000 to the winner. Aidan O'Brien has been unlucky to bump into the brilliant Bow Echo on three of his four starts this year, going down to George Boughey's phenomenon in the 2000 Guineas, St James's Palace Stakes and Sussex Stakes by a cumulative three lengths. Clearly a star in his own right, Ryan Moore's mount cruised to an emphatic triumph in the Irish 2000 Guineas earlier in the campaign and with Bow Echo now retired, is arguably best of the European milers.

Both Opera Ballo and Ten Bob Tony had to give Gstaad 8lbs the last day but that is reduced to 6lbs and both will hope that will be enough to close the deficit of just under three lengths. Opera Ballo is a Group 1 winner this year, taking out the Jebel Hatta at Meydan in January before subsequently topping that up with an impressive weight-carrying display in the bet365 Mile at Sandown against some top rivals.
