Watch a full replay of the MBNA Chester Vase won by Venice Beach at Chester on Thursday and reaction from Aidan O'Brien and Ryan Moore
"We are still learning an awful lot about him.
"He was tight for room and changed his legs. I feel he put the race to bed but then started to look around again.
"He picked up and he won his race. He's still learning about it and it's still early days for him.
"He's a beautiful pedigree and he has a good brain.
"I don't know what the plans are but he's certainly a colt with plenty of potential."
O'Brien suggested afterwards that owners Coolmore would make a decision as to the composition of his team for the Derby at Epsom on June 3 no earlier than next week, with the winner no bigger than 20-1 with Coral behind stable companion and 2000 Guineas winner Churchill at 11-2 with Betfair.
O'Brien said: "I'm delighted with him (Venice Beach).
"We knew that he stays a mile and a half. He's a little bit lazy and a little bit babyish, that's why we felt it would be important to bring him here.
"He's a good bit to learn, but Ryan was very happy with him.
"You learn a lot at this place - a lot of stuff happens very quickly. You have to make room, it can be tight and you have to stay as well.
"The lads will talk about that (the Derby) and decide what they want to do in the next week or 10 days.
"He's a horse that gets a mile and a half and handles quick ground and we think he'll improve."
Of runner-up Wings Of Eagles, O'Brien said: "I'm delighted with him as well. We liked him last year and he had a lovely run in France - he was back a bit (ninth in the Criterium de Saint-Cloud) but it was a lovely run.
"If he was going to be ready for the Derby, he needed to run and he travelled well and settled well."
O'Brien added: "You'd have to be delighted with those three and we'll know a lot more after the one at Chester tomorrow (Cliffs Of Moher, Dee Stakes) and Saturday (Sir John Lavery, Lingfield Derby Trial).
"Those two are only just ready to start back but they looked very exciting types last season.
"They'd had a few little hold-ups in the spring, which is why they've been aimed at the later trials.
"They work like very classy horses at home so we'll see how they do.
"You'd have to hope Venice Beach and Wings Of Eagles will step up on what they've done there, while The Anvil brought the best form into the race and is solid.
"You need them to learn before a race like the Derby and they do that here.
"Hopefully Cliffs Of Moher and Sir John Lavery will improve for their run, but they'll need to."
Saeed bin Suroor, trainer of fourth-placed Tamleek, said: "We didn't really learn much as when he wanted to quicken he couldn't.
"He's a big horse and I'm sure he'll keep progressing.
"A more galloping track will suit. He's in the Derby and the Irish Derby. We'll see how he is and make a decision over which one he runs in."
