Speaking to BBC Radio, the 21-year-old said, "It's a first for me to be involved in one, to take one. I have awful memories kind of growing up and I think the first Euro that I was really interested in was the one against Italy [Euro 2012] with the dink from [Andrea] Pirlo. It kind of stains your memory a little bit, you always think: 'England in penalty shoot-outs, I'm not sure,' but it's really nice to have that experience to add to the locker now.
"I was really confident in my preparation, confident in the things I talked through with Jimmy Floyd Hasselbaink, he's stepped up for us massively. It's the work that he does behind closed doors, with the lads being willing to take on that information, that put us in those situations in order to be able to win."
He added, "So this is a massive team effort. Another thing is [goalkeepers] Dean Henderson, Aaron Ramsdale, Tom Heaton, who have been with us this camp, they've been huge in helping us practise the penalties.
"Again, they won't get the credit they deserve but essentially, if they don't put in the right effort, you don't have the right practice to go out and execute. So many people are involved in this win. It's a massive team win."
