James Ward-Prowse felt England Under-21s lacked the confidence to break down Sweden in their Euros opener.
The Young Lions secured a goalless draw in a game of few chances at the Kielce Stadium.
“It was very tough and I think the opening game in a tournament always is,” explained Ward-Prowse.
“We had a long build-up to tonight’s game and I felt we did well in periods, but maybe as a team we need a little bit more confidence to play.
“We started the game very well, and maybe we need a little bit of luck and a bit more quality to break them down.
The biggest chance of the game came when Linus Wahlqvist was hauled down in the penalty area by Ben Chilwell on 80 minutes to win a penalty for Sweden.
But Jordan Pickford stayed upright to gain all the headlines and deny Wahlqvist from the spot, before saving Carlos Strandberg's follow-up.
“We’re thankful to Jordan for his save and that will give him a lot of confidence,” continued Ward-Prowse.
“Throughout a game you’re not going to be able to dominate for the whole 90 minutes so we have to manage it.
“We realised we were up against a good team, who were going to have periods in possession as well but we dug deep and limited them to few chances.”
