Speaking on Channel 4's The Morning Line Aidan O'Brien said: "St Nicholas Abbey worked with Midas Touch on Friday and worked as well as him but that was the unusual thing, normally St Nicholas Abbey works head and shoulders above everything.
"He did a piece of work on Tuesday and Johnny was over the moon with him but he was a little bit disappointed on Friday morning so we decided to let everybody know.
"The problem with training horses is that everyone is different, there is no rule. His work was good, he worked very well.
"Colm (O'Donoghue) rode Midas Touch and he thought he had improved a lot from Leopardstown so that's also there but usually St Nicholas Abbey is head and shoulders above everything, he's the most incredible worker you've ever seen.
"I suppose it might have just taken Johnny back a bit that he just worked as well as Midas Touch.
"He wasn't disappointing, just not as scintillating as he usually is.
"There is always a possibility that any horse wouldn't run, everything has to be right for them to run in a race like that so you could never say never.
"I think we'll make a final decision in the middle of the week. Obviously we have to decide which horses will go to France. Viscount Nelson will definitely go there and whether something goes with him will be decided in the middle of the week.
"They'll work again on Tuesday or Wednesday, depending on the horses, we'll have the main work done by then.
"The two intended for Epsom were St Nicholas Abbey and Midas Touch, along with At First Sight.
"Jan Vermeer and Cape Blanco had the possibility of going to France too so if there was any doubt about St Nicholas Abbey there is a big chance Jan Vermeer might go to Epsom as well.
"But it's all up in the air and I would say to everybody to just wait and see because we wouldn't want to run him unless we were very happy with him."
O'Brien also refused to rule out the possibility of Kieren Fallon being on board one of his Derby runners.
"Obviously Johnny will ride one and we've got Colm and Seamus (Heffernan) here and the outside jockeys like Kieren and Pat Smullen. There's some very good jockeys available so I don't think we'll be worrying about that," he added.

I topped up yesterday to raise my average to 4.7. Don't know what to do now He's the only one I've backed in the race.

Agree with poster below ... Just the Oaks next year for me unless HRAC or Stoutey have something special in the colts ... Can't be @red with this Circus every year any more.

Reported to have worked quite brilliantly earlier in the week, the son of Montjeu more than disappointed connections on the Ballydoyle gallops yesterday morning, prompting Aidan O’Brien to issue a statement.
Said O’Brien: "Johnny (Murtagh) rode St Nicholas Abbey this morning and felt the colt may not have shown the same sparkle as he had when he rode him on Tuesday morning, therefore he won’t make up his mind what horse he rides in the Investec Derby until the middle of next week."
O’Brien is responsible for the first four in the betting – St Nicholas Abbey, Jan Vermeer, Midas Touch and Cape Blanco.
Murtagh committed to St Nicholas Abbey for Epsom a long time ago but it now looks virtually certain that will be on Jan Vermeer, so impressive when winning the Gallinule Stakes at the Curragh on his seasonal debut, at Epsom.
Jan Vermeer had a choice between the English Derby and the French equivalent at Chantilly and was surely originally earmarked for the latter.
St Nicholas Abbey was undefeated as last season’s champion two-year-old but could finish only sixth behind Makfi in the 2000 Guineas at Newmarket while the other three have all won their Derby trials in impressive fashion.
My information regarding yesterday’s gallop was that St Nicholas Abbey worked particularly badly and coughed afterwards.
Kate Miller from William Hill reported that punters were quickly looking to back Jan Vermeer yesterday.
She said: "Punters have completely forgotten about St Nicholas Abbey."
William Hill have reacted by promoting Jan Vermeer to favouritism, 11-4 from 6-1. They pushed out St Nicholas Abbey from 7-4 to 3-1.
Meanwhile, Frankie Dettori, who broke his Derby duck on Authorized in 2007, has been confirmed as the jockey for Rewilding.
William Hill bet: 11-4 Jan Vermeer, 3-1 St Nicholas Abbey, 7-1 Midas Touch, 9-1 Bullet Train, Cape Blanco, 10-1 Rewilding, Workforce, 11-1 Azmeel, 20-1 bar.
