England captain Leah Williamson admitted her team were "slightly off" during their 2-1 defeat to world champions Spain in Barcelona.
The Lionesses missed the chance to reach the Women's Nations League finals after Claudia Pina's double secured Spain's top position in Group A3.
Alessia Russo had put England in the lead on her 50th international appearance, despite Spanish players claiming that Salma Paralluelo had been fouled in the build-up.
However, second-half substitute Pina made the difference with two goals within 10 minutes, securing Spain's spot in October's semi-finals.
Coming off a 6-0 victory over Portugal and with the European Championship starting next month, Williamson believes there are "tweaks" to be made.
"I think in the second half they pressed a bit higher, we struggled, we couldn't keep the ball as well as we had done in the first half. We didn't really have any real threat," Williamson shared with ITV Sport.
"Under that much pressure against a top side, sometimes that's what happens, they get to you and win the game.
"I think especially first half was a great display, but for the most part we looked solid and we felt solid.
"We feel good, there's just tweaks that need to be made and it's disappointing because that's a competitive fixture and that's an important campaign to us going forward with rankings and seedings.
"I think you saw maybe the best of us the previous game and just slightly off it today."
England manager Sarina Wiegman praised her team's performance, noting the intensity of the match and the opportunities created.
"Very intense game. Of course we know that they're very tight on the ball," she said.
"I think we did well, after the first half they had a little more of the ball, but saw we had the ball a lot too.
"I think we could've been a bit tighter and patient in the first half too, but you could see where we could harm them. I think a couple more times we would not have been offside or play a little quicker behind or switch play quicker, we could've harmed them even more.
"Second half they started really quick, they did something different and pressed really high. We had some trouble to get out of the press and keep the ball.
"Of course they brought Pina in and she was very secure with her shots."
With Euro 2025 on the horizon, Wiegman is gearing up to reveal her squad for the upcoming tournament.
The Lionesses are set to face Jamaica in a warm-up match on June 29 before kicking off their Euros challenge against France in Zurich on July 5.
Wiegman added: "What you've seen this week is that we had a very good week. Players coming back from injuries, players fighting for positions or minutes or selection and I think that's very positive.
"Some will keep training because they need to train, others will take a couple of days off. Then we move forward and come together get ready for Jamaica, then for France."
