The Iron trailed 3-0 at half-time, but fought back to tie the match 5-5 - thanks to two goals in second-half stoppage time - then went on to win the penalty shootout 7-6.
“I can’t think I’ve ever seen anything like that. That has to be the most remarkable match I have ever seen," he said.
“I can’t get my head round it. To be honest it was a horrible game from start to finish and I already feel as though I’ve been through half a season’s worth of emotion.
“We didn’t get a tackle in for 45 minutes but when you are in trouble the only thing to do is go forward and have a go. That’s what we did and by the end of normal time I felt we were well on top.
“I was confident about our first five penalty takers but wondered how it would go when we got down to the next lot, the ones who were hiding and didn’t want to do it. In the event they all looked full of confidence and did the business.”
Nigel Clough, the Derby boss, felt his side would take a massive blow to their confidence after twice blowing a three-goal lead.
“We haven’t even started out League programme yet and we are already feeling rotten," he said.
“This was an absolutely bizarre game. We had enough chances to score 15 goals and that was the main failing as far as I am concerned.”
