Last year's dual Derby hero Camelot tops five Aidan O'Brien-trained possibles for Sunday's Tattersalls Gold Cup at the Curragh.

The four-year-old, who also won the 2000 Guineas at Newmarket last season, was struck down by colic after his run in the Prix de l'Arc de Triomphe but reappeared this season with a straightforward win in the Mooresbridge Stakes.

Also in the mix for the Ballydoyle team is last year's Oaks winner Was along with El Salvador, Windsor Palace and Ernest Hemingway.

Al Kazeem has been given the green light to travel over by his trainer Roger Charlton after a good piece of work on Monday.

Writing on his website, www.rogercharlton.com, the Beckhampton handler said: "We do not have many runners during the week, but Al Kazeem worked impressively with his lead horse over seven furlongs yesterday and he remains an intended runner at the Curragh on Sunday, where he is likely to meet up with the mighty Camelot in the Tattersalls Gold Cup."

Dermot Weld's Ribblesdale winner Princess Highway could still run, despite disappointing in the Blue Wind Stakes last week.

David Wachman's Aloof and Joanna Morgan's Negotiate are the other possibles.
