Jordan Pickford says he had full confidence in his ability to be England's penalty hero after helping them through to the quarter-final of the World Cup.
Pickford produced a superb save in the shoot-out from Colombia's Carlos Bacca.
It helped rescue the blushes of his fellow Sunderland fan Jordan Henderson, whose miss had threatened to send England out.
But Pickford showed his 'power and agility' to produce a stunning one-handed stop to deny Bacca before Eric Dier sealed the win with the crucial kick.
Washington-born Pickford said: "We did our research on them with Marge, the analysis staff. We had a fair feeling - Falcao was the only one who didn't go his way.
"But you set, react and go power. I've got power and agility. I don't care if I'm not the biggest keeper, I've got that power and agility to help me get around the goal and I'm very good at it.
"It's about getting there and being in the moment - and I was."
Harry Kane had earlier given England the lead with a 58th minute penalty only for Yerry Mina to head home an injury-time equaliser just seconds after Pickford pulled off an incredible save.
After a goalless extra time, it went to penalties. England had never won a World Cup shootout and looked to be heading for another defeat when Henderson had a penalty saved by David Ospina.
But Mateus Uribe smashed the following kick onto the crossbar to pave the way for Pickford and Dier to be England heroes.
Former Sunderland stopper Pickford, who came in for some criticism by pundits after the Belgium defeat in the group stage, has developed a reputation for saving penalties during his time as an England youth international.
Dier said: "Jordan is a fantastic goalkeeper and deserves everything. His attitude is brilliant and he's been brilliant in training and taken it into the game."
