The only fly in the ointment for Latrobe is that he needs a travelling companion to keep him focused and comfortable in his time away from his Irish base.
The Williams camp is hoping that another O'Brien horse, Master of Reality, will be able to accompany him in quarantine, but if not arrangements could be made for another foreign horse based at Werribee to be his companion.
That aside, Nick Williams believes that Latrobe has more class and brilliance than Rekindling and could, if he gets to Flemington on Cup day, be a threat.
Speaking after watching his horses Yucatan and The Cliffsofmoher work at Werribee on Thursday morning, Williams said of Latrobe, who won the Irish Derby earlier this year: ''He is coming out, Brenton has been engaged to ride him, Joseph is very happy with him.
''Joseph thinks the horse has really thrived so he's keen to bring him. We are also very wary about taking his mate away from him, so we need to get his mate on the plane with him.
''Rekindling was a natural stayer, a little horse who just stayed. He didn't take much work in hindsight, was very sound in the mind.
''This horse is still a work in progresss. But I think he's got the potential to be a better horse than Rekindling.
''This horse is going to be a very good four-year-old, but mentally he's probably not quite as ready as Rekindling. But Joseph thinks the last few runs have really brought him on.
Despite his need for a travelling companion, Williams says Latrobe is not a particularly difficult horse.
