The multiple Group 1 winner is 'definitely a Guineas horse' according to his jockey Ryan Moore.
Aidan O'Brien's stranglehold on the ante-post market for the first Classic of next season was strengthened further on Saturday as Churchill shortened in the market after a comfortable victory in the Dewhurst.
As big as 3/1 in the week leading up to Saturday's Group 1, bookmakers reacted to Churchill's romp by hardening the son of Galileo to as short as 6/4 in places for May's Classic.
O'Brien, who in landing Saturday's prize was securing his 20th worldwide Group One Flat race of the year, said of the winner: "They went a sensible pace. He settled in there and quickened down into the dip.
"It got a little bit messy after the two [furlong marker] but Ryan guided him through and produced him lovely, so we're over the moon.
"Physically he's a very imposing horse. He's probably a more imposing two-year-old than we've ever trained.
"He has a great mind and relaxes and sleeps. He just does the minimum, which is brilliant. He's a great traveller and the qualities are there in abundance.
"Anyone that has had anything to do with him gets that special feeling from him - that's very special when that happens.
"We've always viewed him as a miler, but that's not to say he won't get further. He's so relaxed and laid-back and when he came in (to the winner's enclosure) he wasn't even blowing. He's very economical as a galloper - he saves everything."
Jockey Ryan Moore who has ridden the 2yo on all but one of his 6 starts to date said after the race: "He was always going to win. He's a very, very good colt. It wasn't as evenly-run as it should have been, but this lad has got an awful lot in his favour.
"There's not a lot he can't do. When I ask him, he always finds. He's definitely a Guineas horse. I think he'll get better."
Churchill was O'Brien's fifth Dewhurst winner, but surprisingly only one of the previous four has gone on to land the 2000 Guineas the following year - Rock Of Gibraltar back in 2002.
