The match was even and the first half seemed to end goalless.
But then he stepped forward.
Nicolas Stefanelli ran into the penalty area and nodded the ball into goal.
The full hit was the only one of the match and he thus became today's great hero at Friends arena when AIK defeated Djurgården 1-0.
- Unbelievable.
It is beautiful and wonderful to play at home in front of our audience.
We can dedicate this victory to them, he says to SVT Sport.
- It is a great joy to win in front of the home crowd - such an important match.
Now we have to enjoy before it's time for the next match.
It's great to score a goal as well.
You enjoy extra when it's a derby.
"Is about being in the right place"
He describes the goal:
- I got the ball from Bilal (Hussein).
We made eye contact and he slammed it in the middle.
I came in well with my head.
I train a lot on it, to be in the right place.
You are basically the shortest on the plane, yet you manage to nod it in?
- It is unbelievable.
Against Hammarby last year, I did the same.
It is important to be there, in the right place.
Otherwise there will be no goals.
Big praise from the coach
AIK coach Bartosz Grzelak was pleased to get three points in the important meeting with Djurgården.
He is extra happy for Stefanelli in particular - who gets real praise.
- "Nico" does everything for AIK and is incredibly loyal to the team.
I do not know how many runs he makes at home, but he wears out enormously.
I'm so incredibly happy for him.
It was so incredibly traumatic for him last time when he decided against Djurgården and took off his shirt and was sent off, says Grzelak at the press conference after the match.
- The first thing he does when he steps out is that he gives tips to those who come in.
He's a great player.
It's a soldier.
He does everything necessary for AIK to win football matches.
