Prix du Jockey Club winner Intello successfully dropped in both trip and grade when winning the Prix Messidor on Sunday.

The French Derby winner was immediately quoted for the Prix de l'Arc de Triomphe following his Classic success at Chantilly but connections didn't appear convinced, nominating the Prix Jacques le Marois over a mile as the initial aim.

The three year old duly lined up in the Group Three at Maisons-Laffitte to see how he fared over a straight mile ahead of a possible run in the Marois.

Sent off the 2/7 favourite, Intello was settled towards the rear of the six runner field by Peslier before creeping closer to the pacesetting stablemate Prince D'Alienor and Don Bosco.

He readily picked up when asked and only needed to be pushed out to record a one and a half length success with Mainsail staying on for second.

Intello has now won five of his six starts with his only defeat coming when an unlucky-in-running third in the Poule d'Essai des Poulains.

Pierre-Yves Bureau, racing manager to the owning Wertheimer brothers, confirmed that the Marois remains the target and refused to be drawn into ruling Intello either in or out of the Arc.

"If the horse comes out of the race well we will go for the Jacques le Marois now (Deauville, August 11). That has been the aim," he said.

"He ran a very nice race today. He was giving four kilos to the others and he was the only three-year-old in the race. All went well, so we are delighted.

"We will see. We want to go step by step. We wanted to drop him back to a mile and then go for Jacques le Marois. After that we will talk with Andre Fabre and decide.

"It is a little bit too early to talk about the Arc. Of course it is one possibility, but we think it is too early to say anything about that. We will see after the Marois if we can win that. Then we will decide the programme for the rest of the season."

He is a 5/1 chance with Sky Bet for the Arc and the Leeds' firm's spokesman Michael Shinners said: "He was very impressive in winning his race and looks to be a huge player in this year's Arc. My only concern would be the trip, but I am sure we will have a better idea after his next run."
