The Irish St Leger and the Melbourne Cup are potential options for Royal Diamond following his superb run in Saturday's Ebor at York.
He ran a fantastic race to be beaten just a neck by Godolphin's Willing Foe in a thrilling climax to Europe's richest handicap.
The six-year-old joined Irish trainer Tommy Carmody from Jonjo O'Neill earlier this year and arrived on the Knavesmire having won once and having been placed on three other occasions this season.
Tim Jones, racing manager for owner Andrew Tinkler, said: "We were absolutely delighted with him.
"It was a great achievement by Tommy and all his team and the horse has done nothing wrong all year.
"It sounds strange to say a six-year-old is progressive, but he does seem to be getting better all the time.
"The Ebor has been the plan all the way through the year.
"We wanted to make sure he got a high enough rating to get into the race."
Jones added: "We went there feeling he would run a good race and he did, so we're thrilled with him.
"Everyone will have a proper discussion about what we're going to do with him.
"He's in the Irish St Leger and I think he will be given an entry in the Melbourne Cup as that race has been an option for him all year.
"That's on the table if we decide to go that way, but we'll see."
