He not only produced a stunning save in normal time but also prevented Carlos Bacca from scoring in the penalty shootout.
"But I understand why Gareth did it, it's the first thought at the time that you've got to defend and hang onto what you've got, but I thought besides that England were very composed".
"I don't care if I'm not the biggest keeper", said Pickford afterwards.
Substitute Dier was relieved to see his penalty squirm past David Ospina, after missing a great chance to seal a last-eight spot in extra time.

"The more games you play the better you become". We've got an outstanding mentality.
"Jordan Pickford proved in the last game how big he is for this team and we will all be celebrating together", he said.
England are now joint second favourites alongside France to win the tournament at just 4/1, according bookmakers Ladbrokes.
