That Angeldahl became the decisive factor at the beginning of the second half was completely logical. A slow-starting Sweden had not created much at all until then - apart from two fine Angeldahl chances in the first half.
In the second minute, a Danish defender was in the way when the Real Madrid midfielder was on the verge of giving Sweden a dream start. Just before the break, it was then Denmark's goalkeeper Maj Bay Østergaard who made a great save when Angeldahl's free kick cannon was heading towards the crossbar.
But in the 55th minute, Østergaard had to give in.
Angeldahl played a nice one-two with Kosovare Asllani and then scored 1-0 in the far corner.
A relief and an incredible feeling. I felt that I should have had a goal already before my goal came. And finally, when I get that chance after a one-two with "Kosse" and it finally sits, then there are so many emotions that come out, says Angeldahl.
The match hero was not completely satisfied with Sweden's play, but means that it plays less role.
A premiere is always a premiere. It's extra nerves. But I think it's important to win the first match and get a good feeling in the group. And release some of the pressure. It couldn't be better.
Gold-thirsty tifo
A few thousand Swedish fans marched in a united troop to the match arena in Geneva. Before kick-off, the yellow-clad short side unfolded a large tifo adorned with two Swedish football legends. On one half: Anette Börjesson, captain when Sweden's women's national team won its only championship title so far, in the European Championship 1984.
On the other: Kosovare Asllani, current captain who made her 200th A-international match in Friday's premiere.
And the text, an echo of what the Swedish players have repeated in the weeks leading up to the European Championship: "41 years since last - the gold must go home".
But until Angeldahl's 1-0 goal, the Swedish game did not impress significantly. The 6-1 win over Denmark in the Nations League a few weeks ago was just a memory.
In the end, however, it's about winning matches, not how it's done, and there was no doubt which was the best team at Stade de Genève. When the zero was finally broken, the Swedish players also seemed to shake off the premiere nerves.
Stina Blackstenius was a few centimeters from extending to 2-0 when a corner fell at her feet, but Frederikke Thøgersen threw herself into her own goal and pushed the ball away on the goal line.
Rib shot from Harder
Andrée Jeglertz' Denmark mostly lacked the edge to really threaten Sweden, but they do have Pernille Harder. The Bayern München star can create a lot from very little and with ten minutes left, it almost gave a Danish equalizer. Harder broke in from the side and fired her left foot - into the crossbar.
Denmark did not get any closer.
With the win, Sweden takes a big step towards the quarterfinals. Three new points against the group's presumed whipping boy Poland on Tuesday and the advance can be clear already before the group stage finale against world third Germany.
