Proportional has a lot to live up to compared with last year's Total Prix Marcel Boussac winner Zarkava, but still had the ability to humble a decent pack of two-year-old fillies in the Longchamp Group One.

Rather than stay at home for the French 1000 Guineas next season like the new Prix de l'Arc de Triomphe champion Zarkava did, Proportional's Anglophile trainer Criquette Head-Maarek could be persuaded to aim for the Newmarket version, as Finsceal Beo did in 2006.

Stephane Pasquier was in the perfect spot close to the pacemaking Marquesa, and Proportional (20-1) quickened off the home bend to come in three lengths clear of Jean-Claude Rouget's previously unbeaten Elusive Wave.

David Wachman's Moyglare victor Again was quickly too far back to make an impression.

Proportional, owned by Prince Khalid Abdullah, is a 6-1 shot for the Guineas with Stan James.

Considering Newmarket, Head-Maarek, now five times a Boussac winner, said: "Why not? She'll be entered in the 1000 Guineas and she will tell me what to do. She's the boss.

"The first time she ran in Deauville I thought she was a very good filly, she was my best and I thought she would win that race.

"She didn't understand what we asked her at Deauville. She was green, then I ran her again and she won very well at Chantilly.

"I asked the Prince if he would let me run her here and I think we did the right thing."

Jean-Claude Rouget said of the runner-up: "It was a very good performance and I bought her from Richard Hannon earlier in the year.

"She is finished for this season now and we'll now try and get her ready for the Guineas."
