RACING'S class of the giants between champion colts Dubai Millennium and Montjeu could take place in York.

Dubai Millennium's owner Sheikh Mohammed has issued a challenge to Michael Tabor, owner of Montjeu.

He is offering to run his Dubai World Cup winner against the French-trained four-year-old over 10 furlongs for $6million (£4m) a side.

Possible venues for the historic challenge are York on August 24, Newmarket on August 26 and Ascot on September 23.

Sheikh Mohammed has also pledged that if Dubai Millennium triumphs half of the winning prize-money will go to a charity of his opponents' choice.
