Epsom Derby hero Workforce bounced back to form and gave trainer Michael Stoute his first success in the Qatar Prix de l'Arc de Triomphe at Longchamp.
The King's Best colt travelled strongly throughout in the hands of champion jockey Ryan Moore but was still nearer last than first on the turn for home.
However, he showed an excellent turn of foot given the testing conditions to hit the front approaching the final furlong and dug deep in the closing stages to repel the sustained challenge of Nakayama Festa. Sarafina was third.
Workforce was a brilliant winner at Epsom, where he broke the course record, but his Arc participation remained undecided until Thursday following his dismal performance in the King George VI And Queen Elizabeth Stakes at Ascot on his previous start.
Japanese raider Nakayama Festa ran a fantastic race, pushing the winner all the way to the line but just losing out following a stirring battle.
Sarafina was the one that finished best of all in third but the race was already over and she had to make do with minor honours.
