Nicholls said: "I enjoyed that, I thought he was awfully unlucky the last day. The rain suited him and I thought he'd go close today."
Nicholls went on: "The rain suited him rather than Bouvreuil, who didn't stay on the ground.
"Frodon's a good horse, he jumps well. They can all make the odd mistake, he's only a novice, but we put that right in the last month and he was a lot fresher today. He'd only run seven days before the BetVictor.
"The great thing is he is still a novice, we will mix and match but today was the day.
"It was great for Sam to have a winner on the big stage. It will have done his confidence the world of good."
Venetia Williams, trainer of runner-up Aso, said: "He's winged the last and beat all the horses from the BetVictor apart from Frodon, who didn't run his race."
Village Vic's trainer Philip Hobbs said: "He's a 100 per cent trier. He ran on very well in the end. He's run fantastic again.
"The great thing about him is he gets into a rhythm and jumps well. Although his jumping was good, I don't think it was quite as good as last time. He was very brave and is good at organising himself."
