A six-length runner-up to New Approach in the race last year, the Khalid Abdullah-owned four-year-old is a 9-2 chance with Bet365.
But Cecil, who has won the race twice before, said: "A lot depends on the ground. He is in great form and I'm very happy with him, but he's also in the Group 3 Darley Stakes at Newmarket on Friday and he could run there instead. We'll see."
The 10-times champion trainer and winner of 23 British Classics revealed he is in no rush to see his 15-year-old son Jake follow in his footsteps.
Cecil said: "I'd hate him to start training. It's a very expensive business.
"I'd like him to be a landscape gardener, but he's a very good actor. He could be the next Richard Gere. I'd like that."
