Dunaden has has a familiarisation gallop at Epsom ahead of next weekend's Coronation Cup.
The 2011 Melbourne Cup winner returned to Australia last year to win the Caulfield Cup over 2400m, the same distance he will run at Epsom.
Having finished fourth to St Nicholas Abbey in the Sheema Classic at Meydan in March, the Mikel Delzangles-trained entire was beaten two lengths into third by Pastorius in the Prix Ganay on his European return.
"Jamie (Spencer) was quite happy with him and I was pleased he could have a look at the track," Delzangles said.
"The race didn't go as planned in the Ganay, but he looks like he's getting quicker as he gets older.
"I was quite impressed with the way he won at Caulfield last year."
Dunaden will meet St Nicholas Abbey once more in the Epsom feature as Aidan O'Brien's six-year-old looks for his third win in the race and sixth Group One in total.
