Our ratings expert looks back at the action from Chester

Cliffs Of Moher maintained his position as second favourite for the Derby with a convincing if unspectacular success in Friday's Dee Stakes at Chester, although it was not a performance that dramatically improved his form chances and a Racing Post Rating of 108+ needs a lot of improving upon if he is to play a starring role at Epsom.

Key to the Dee Stakes form is the proximity of the front-running and surprise improver Max Zorin. An RPR of 103 fits with the race standard, as does that of slightly improved runner-up Bay Of Poets (105).

Bay Of Poets provided a further boost to the form of Dante favourite Cracksman's Investec Derby Trial defeat of last weekend's Newmarket Stakes winner Permian.
