Cirrus Des Aigles looked every inch a superstar as he blew away the opposition in the Prix Ganay at Longchamp.
Corine Barande-Barbe's six-year-old (8-13 favourite), seeking his first victory at Group One level in his own country, was sent straight to the front by Olivier Peslier and dictated the pace throughout the extended 10 furlongs.
Peslier gradually wound it up and had the rest of the field struggling by the time they turned into the straight, before coming away from nearest pursuer Giofra to win easily under hands and heels riding. Reliable Man finished third, with Michael Bell's challenger Wigmore Hall a never dangerous fourth.
Barande-Barbe said: "We are very proud of him - he is a magic horse. We have been waiting for that (his 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."
Cirrus Des Aigles could return to British shores this summer, with the Coronation Cup at Epsom and the Prince Of Wales's Stakes at Royal Ascot possible options before he defends his Champion Stakes crown.
The trainer went on: "We will consider what to do next. There is the Coronation Cup, Royal Ascot, the Grand Prix de Saint-Cloud and Singapore to consider.
"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.
