Aidan O'Brien is pleased with where he is at with Gleneagles ahead of his attempt to further cement his position as the best miler of his generation in the St James's Palace Stakes at Royal Ascot on Tuesday.

The three-year-old has conquered all before him on his two starts this season, with victories in both the English and Irish 2,000 Guineas.

O’Brien, who is chasing a record-breaking seventh success in the race but his first since 2009, feels his latest stable star is in good order as he faces five rivals in his quest to complete of hat-trick of victories at the top level this year.

O'Brien said: "We're happy with him since the Curragh and everything has gone well.

"We were a bit worried about the ground at the Curragh and hopefully we'll get good fast ground at Ascot.

"Joseph (O'Brien) rides him every day and seems very happy with him.

"Since the first day when he was fourth in a maiden at Leopardstown, every other day he's been very straightforward.

"He's relaxed now and doesn't do much when he gets to the front. He travels well and quickens well and is a lovely horse."

The sternest opposition for Gleneagles looks set to come from the Andre Fabre-trained French 2,000 Guineas winner Make Believe, who was supplemented at a cost of £35,000.

Although tasting defeat, and losing his unbeaten status, when finishing second in the Prix Djebel at Maisons-Laffitte, the son of Makfi bounced back when making all to defeat subsequent French Derby hero New Bay in the French Classic at Longchamp last month.

Fabre said: "Make Believe has done well since making all the running in the Poule d'Essai des Poulains, though I have not done much work with him as he is quite a light horse. But I am very happy with his condition.

"Fast ground would not be a real concern for him as Ascot always does a good job with the ground and it was pretty fast when he won the Poulains, but a drop of rain would be welcome.

"He does not need to lead, he could come from behind, too - we will just see how the race develops and I will leave that to his jockey, Olivier Peslier.

"I see Make Believe as a real miler and I expect him to remain at this distance for the rest of the season.

"I was very impressed with Gleneagles in the 2000 Guineas; impressed with his confirmation, with his action and with his attitude. He looks something special and will be difficult to beat."
