Trainer David Vandyke dropped a bombshell over the weekend after he informed Endresz he was no longer interested in training for the polarising businessman.

Endresz said the shock announcement had caught him off guard.

"I didn't see it coming," Endresz said.

"I rang David and had a chat with him about what led to his decision.

"The reality is he chose his partner and foreman Emma Lehmann over Alligator Blood.

"There had been tension building between my Uncle Jeff and Aunty Robyn and Emma during Alligator Blood's Golden Eagle campaign.

"It led to a falling-out and Emma leaving Sydney to return home to Queensland.

"I posted what David told me on social media on Sunday night.

"I probably didn't want to air my dirty laundry.

"But if I didn't explain what happened and just said we parted company, there is no doubt the blame would have fallen on my shoulders which isn't the case."

Alligator Blood is set to undergo surgery this week after recently being diagnosed with kissing spine which Endresz believes led to his below par performances during the spring.

The son of All Too Hard is expected to be sidelined for four months.

Endresz said he wouldn't be rushed into making a decision on a new trainer but wanted to go to either a Melbourne or Sydney stable.

"It's fair to say over the past 48 hours that I have learnt how ruthless the racing industry is," he said.

"I have had 14 different stables ring me expressing their interest in training 'Al'.

"But I'm not in a hurry to make up my mind because 'Al' has surgery this week and won't be able to race for around four months."

Endresz said he had already made alternative arrangements for several other of his promising young gallopers including Wolf Moon, Crypto Tycoon and unraced two-year-old Bronze Dragon.

Stradbroke-winning trainer Nat McCall and emerging horseman Billy Healey will take over the training duties of the other gallopers owned by Endresz.

"I've decided to give young Billy Healey an opportunity to train some of my well-bred youngsters," he said.

"Billy's delighted and thinks he has just won tattslotto.

"Nat will also get some nice horses so she is thrilled as well.

"Billy actually purchased Bronze Dragon at the sales but couldn't find a syndicate to pay for the horse.

"So we bought the horse off Billy and ironically now he is the new trainer."
