French star Cirrus Des Aigles claimed his first Group One prize in his homeland with an impressive display in the Prix Ganay at Longchamp.
Corine Barande-Barbe's pride and joy beat So You Think to land last year's Champion Stakes at Ascot and he collected his second top-level victory in last month's Dubai Sheema Classic on World Cup night at Meydan.
Coming back to a mile and a quarter from a mile and a half on his return to the European scene, the six-year-old gelding was soon in front under Olivier Peslier, with the jockey happy to let his mount stride on.
Cirrus Des Aigles upped the tempo heading into the false straight and it was soon clear that his rivals were struggling to keep up.
While the remaining riders got to work, Peslier was sitting pretty on the 8-13 favourite and pushed him clear for an authoritative success.
Alain de Royer-Dupre's Giofra finished best of the rest, with Reliable Man third and Michael Bell's British raider Wigmore Hall fourth under Hayley Turner.
Barande-Barbe said: "We are very proud of him - he is a magic horse. We have been waiting for that (first Group One in France) for a long time and he won so easily.
"Olivier gave him a very good ride. Now the horse knows more about racing, you can just let him do what he wants.
"It was a fantastic performance and we are all delighted. We will consider what to do next. There is the Coronation Cup, Royal Ascot, the Grand Prix de Saint-Cloud and Singapore to consider."
Barande-Barbe added: "He has not had a hard race today and we will make a decision about the next place to go with him.
"It would be great to go back to Ascot at the end of the season for the Champion Stakes again."
There were two other Group races on the Longchamp card, with Trois Lunes recording a narrow victory in the Prix Vanteaux and Usuelo running out a comfortable winner of the Prix De Barbeville.
