Aidan O'Brien believes Frozen Fire and Washington Irving provide him with the best chance landing the Ladbrokes St Leger for a fourth time this century.
The Ballydoyle handler launches a five-pronged attack on the final Classic of the season and is confident Irish Derby winner Frozen Fire has the quality to follow up under Johnny Murtagh.
"Frozen Fire is a horse who has always shown a lot of class and just got beat in the Dante (by Tartan Bearer)," he said.
"He then got caught back at Epsom in a slowly-run race, but then went to the Irish Derby and we all saw what he did there. We were delighted with him that day and have been happy with him since.
"We think Washington Irving stays well and his last race was a mile-and-a-half Group Three at Leopardstown.
"Two horses went past him and he stayed on again to be second and you would think the mile and six would suit him well.
"He is a horse who is progressing all the time and getting stronger every day."
O'Brien is also represented by Alessandro Volta, Bashkirov and Hindu Kush.
