The West Ham youngster was his side's hero in the Under-21 League Cup win over Hull City.
The Hammers had appeared to be on the way to success in the Under-21 League Cup on Wednesday as they led 1-0 into stoppage time.
However, a late goal from Hull City saw the tie go to extra-time, and then the lottery of penalties.
All but one was converted by both sides, as Spiegel proved to be the difference by saving from Daniel Batty and securing the trophy for his team.
He was naturally delighted to have been the hero of the hour but insists he was always confident because he was prepared.
“It’s a great feeling. I was confident for the penalties, because I was prepared,” he told whufc.com.
“I watched their penalties [before the match] and I was confident I was going to save one or two. I was close to the first one and the second one I saved.”
“Our players did the job, and it’s not easy to score a pen, especially in a final. They did brilliantly.”
West Ham will now be hoping that some of these successful youngsters can break through into the first team in setup in future.
Manager Slaven Bilic has certainly demonstrated his willingness to give youth a chance this season, handing Reece Oxford his debut against Arsenal.
He will be their inspiration, and they will be hoping this cup win has caught the manager’s eye and convinced him to give more their chance next season.
