The seven-year-old has shown his best over middle distances over the last four seasons, with a previous foray over two miles ending in a distant last to Trueshan in the 2020 Long Distance Cup at Ascot.
However, Broome roared back to winning form over the staying trip on Saturday, seeing off Siskany by a neck in the Dubai Gold Cup at Meydan – his first victory since last year’s Hardwicke Stakes.
That run has put him on course for a clash with stablemate and reigning staying champion Kyprios at Ascot in June, with O’Brien believing he is an ideal candidate to head in Flemington in November.
He said: “We were very happy. Obviously he’s going to go the Cup route and we’ll look at all those races on the way down to the Melbourne Cup. That’s probably what we’re going to do with him.
“He won’t have to run in the two Irish trials, he can go straight to Ascot. After that he can do Goodwood and all those types of races and then finish off down in Australia.
“He’s seven now and he’s the perfect age to be doing all those races, travelling as an older horse.
“He’s an amazing horse, he was very genuine at Meydan. Looking at him, you’d say we should have stepped him up in trip a lot earlier.”
