Good, who is hoping to continue his loan spell at Valley Parade past the February 2 expiry, was overawed following Tuesday night's result after it allowed the club to create history even though they were beaten 2-1 by the Premier League's Villa in the second leg.
"It was the best moment of my life,'' the former Melbourne Heart man said. "It's been over 100 years since Bradford won a trophy, and it doesn't get much bigger than playing at Wembley.
"I'm pretty confident of staying and I can't see it not happening. It comes down to what Newcastle wants, and what they think is best for me.
"I'll do whatever I can to break into the first team at Newcastle, but I'd probably just play reserves in the meantime so it's probably best for me to stay here.
"Last time my loan was extended, it was sorted a day before it was due to finish. So I'm guessing this will be similar.''
Despite the fortune of making it through to the final, Good may lose his starting spot at left-back to fellow Aussie James Meredith who is currently sidelined with a bout of glandular fever.
