Frankel will face a maximum of nine rivals when he switches up to a mile and a quarter for the first time in Wednesday's Juddmonte International at York.

Frankel is set to be joined by his regular pacemaker and three-parts brother Bullet Train, as well as his stablemate Twice Over, who won this prestigious Group One prize 12 months ago.

Frankel's main danger will be the Aidan O'Brien-trained St Nicholas Abbey, who was only third in the King George VI And Queen Elizabeth Stakes at Ascot last time out.

Godolphin's Farhh chased home Frankel in the Sussex Stakes at Goodwood and is set to reoppose, but given the ease with which he was brushed aside, it would be a big surprise if he could reverse the placings.

Nathaniel has won the Eclipse and been second in the King George this year, so he would be an obvious threat if he does line up, although his participation has not yet been confirmed.

Planteur and Sri Putra complete the list of confirmations.
