"We gave him a couple of easy weeks after the John Porter and now we are revving him up for Epsom.
"We felt it was worth having a go over a mile and a half, just to try something different more than anything, especially now he has fully matured. It might be that he is better over further, but we can always go up in trip later on.
"I always thought the Coronation Cup could present a decent opportunity and we are keen to have a go.
"I have never had a runner in the race and it will be great to be there, provided the ground isn't too quick."
