Christophe Soumillon has told connections that he will not ride Dabirsim in the future believing that he and last year's leading juvenile 'lack chemistry'.
Soumillon gives up ride on beaten favourite
Christophe Soumillon has brought an end to his partnership with Dabirsim following the colt's defeat in the French 2000 Guineas at Longchamp on Sunday.
The Belgian jockey told Paris-Turf that he lacked "chemistry" with the Christophe Ferland-trained three-year-old, who won two Group Ones for Frankie Dettori in an unbeaten juvenile campaign.
Soumillon has twice been out of luck aboard Dabirsim, who finished sixth in the French Classic at the weekend after he encountered desperate trouble in running.
Big Mistakes
"I called the owner Simon Springer on Tuesday morning and I explained to him that I would prefer not to ride Dabirsim anymore," said Soumillon.
"I have gone over my two rides on him and I don't think I've made any big mistakes but you have to look at the facts.
"For some reason which I can't explain, I don't seem to get on with the colt.
"I'm not superstitious but the results speak for themselves - the chemistry isn't there between us.
"Regarding the horse and his connections, I think it's best for me to step aside and hope that the next jockey can help him rediscover his sparkle.
"I was very frustrated with how things turned out on Sunday and it's best not to continue."
No Rush
Ferland is in no rush to make any firm decisions about who will ride Dabirsim on his next racecourse appearance.
He said: "There are plenty of able riders and the horse is not going to be running very soon, so we have some time to make a decision."
The French trainer admits his charge is not 100% after his luckless weekend run and is keen to give him time before deciding on his next target - which could still be the July Cup at Newmarket.
Ferland said: "The horse is just all right after his run on Sunday.
"He is not perfect after getting stopped in his run, but he will be OK.
"We will see how the horse is before we make any plans for him.
"There are plenty of options for him - there is the July Cup, the Prix Jean Prat and the Prix Maurice de Gheest. We will see first how the horse recovers.
"At the moment his best trip is seven furlongs and he can run over six furlongs, too, but I think he will stay a mile when he gets stronger.
"Next time he runs, we want him to have a nice run without having to break his action."
