Golden Horn has been added to Sunday's Qatar Prix de l'Arc de Triomphe at Longchamp, with owner Anthony Oppenheimer stumping up the €120,000 fee as expected for the Derby, Eclipse and Irish Champion Stakes winner.

Also supplemented were Shahah, as a pacemaker for the hat-trick seeking Treve, and Spiritjim.

That means a field of 18 is likely for Europe's most prestigious race.

John Gosden has taken out Jack Hobbs, but as well as Golden Horn he still has Eagle Top in the race.

They are the only two contenders from Britain.

Eagle Top earned his place with a terrific effort in the King George VI And Queen Elizabeth Stakes at Ascot in July when losing out by a nose to Postponed, although he has since been beaten by The Corsican at Newbury on very testing ground.

The only other withdrawal was Freddy Head's Migwar.

The three Irish contenders are the fillies Found and Tapestry from Aidan O'Brien's Ballydoyle yard and Dermot Weld's Free Eagle.

Heading the home team, along with Treve of course, are Andre Fabre's New Bay and stablemate Flintshire.

Dolniya, Erupt and Prince Gibraltar are others in the mix.
