The second favourite currently in the Arc market and clear threat to Enable is Aidan O'Brien's Japan who was an expensive recruit for the yard bought for 1.3 million Guineas but this season has started to repay that.
As a two year old he showed clear signs of potential when scoring on his final start as a juvenile in the Group 2 Beresford Stakes.
As a three year old Japan has turned into the horse everyone thought he would be still taking some time to find his feet at the start of this season campaign when fourth in the Dante Stakes on debut.
However, from there it has been nothing but progression finishing a narrow third in the Epsom Derby and has since been unbeaten in his last three starts.
The first was at Royal Ascot in the Group 2 King Edward VII Stakes where he hacked up and really made a statement, since then he has landed back to back Group One contests.
The first over the course and distance of the Arc at Paris Longchamp in the Grand Prix de Paris and his latest and arguably his best performance to date when staying on well to land the Juddmonte International at York.
This again will be his toughest test to date having to take on Enable but the three year old looks to hold the strongest chance in the field.
