Suddenly Christian Eriksen collapsed on the lawn - and few realized the seriousness.
One who did, however, was Simon Kjaer.
The Milan captain called for medical attention and was quick to come and put his friend in a stable side position and open up his airways.
The Daily Mail writes, among other things: "The European Championships 2020 already have their hero and that is Simon Kjaer"
When the medical staff was on site, he went over and supported the affected Eriksen's wife.
"A true captain"
Inter player Nicolo Barella was also quick to pay tribute to the 32-year-old.
"Beyond the colors, well done Simon.
A true captain and a real man ", he writes.
In Spain, Kjaer is described as a man who was transformed from captain to hero, by Spanish Marca.
"They are really good friends"
Denmark's national team captain Kasper Hjulmand told at a press conference after the match that Kjaer was strongly affected by the incident.
- Simon was deeply, deeply touched.
Deeply touched.
He doubted he could continue and gave it a try.
But it did not work.
And that is completely understandable, he says.
- They are really, really good friends.
The Danish Football Association announced yesterday that Christian Eriksen's condition is stable.
He remains at Rigshospitalet Hospital in Copenhagen for further examinations.
