In saving the penalty, Pickford became the first England goalkeeper to save a penalty in a World Cup shoot-out since David Seaman against Argentina in 1998.
"It's something they can look back on and draw on as an experience", Southgate said to ITV.
"If lads want to talk or need help, I'll be there to talk to them or go through the gaffer and we work it out like that". "I don't care if I'm not the biggest keeper because it's about being there in the moment and making the save, and I was", he said after the tie.
It was England's first win in a knockout game since 2006 and earns them a quarter-final with Sweden, who were far from impressive in beating Switzerland 1-0 earlier on Tuesday.
"Just set, react and go". "I might be young but I've got good mental strength and experience and I used that today".
The save gave England's Eric Dier a chance to win the shootout, and he converted. Obviously we knew that England's history with penalties hasn't been great. He missed a penalty against Germany at UEFA EURO 1996, and the nightmare resurfaced after England qualified from Group G this time around.
Russian Federation take on Croatia for the chance to play either Sweden or England in a semi-final.
"When it went to penalties, we had a lot of people around us like, "hmmm".
"I think England will at least make the semi-final this year and it's going to be fantastic". In France, Kane played in every match but didn't score a goal and is mainly remembered for his inability to take a corner.
"This round is looking very nice for us - Sweden is the best chance and then hopefully Russian Federation get through and we play them in the semi-final".
