St Leger winner Kingston Hill deserves to be entered into the Prix de l'Arc de Triomphe, says trainer Roger Varian.
The three-year-old colt won a first Classic for Varian and jockey Andrea Atzeni at Doncaster on Saturday.
"We have to make sure he bounces back from that big effort," the Newmarket trainer told BBC Radio Cambridgeshire.
"But if I'm happy that he's 100% ready to go again, he more than deserves his place in the line-up. It will be on the agenda as long as we're happy."
There were doubts over whether Kingston Hill would feature in the St Leger because of questions over his form on firm ground.
But he came from deep to secure a fourth win from seven career outings and help ease the disappointment of finishing second in the Derby in June.
With the Arc on Sunday, 5 October, Varian will hope for softer conditions at Longchamp for Europe's most lucrative race, with a 5m euros (£3.99m) prize pot available.
"We won the race on Saturday so we can't complain about the ground, but it was still quicker than ideal," he said.
"I think he'll be a better horse when he does get his conditions, which is softer ground. Three weeks from now you hope we get some of that autumn rain through and that will suit him even better."
Varian took over at Kremlin House Stables in February 2011 from Michael Jarvis, who was a 1989 Arc winner with Carroll House and died three years ago.
And Jarvis's former assistant said it was a relief to win a Classic within the first four years of his career.
"I don't feel different. It's sinking in. I feel it's great to do it early in my career and I hope we can add more classics in the years to come," he said.
"It takes a bit of pressure off. It's like a golfer winning a major or a tennis player winning a Grand Slam. It's a little bit more special than your average Group One."
