Sweden immediately showed that they wanted to get three points when there was an international match at Borås Arena and initially created several sharp goal chances.
And it only took 20 minutes - then the first goal was scored.
Patrik Wålemark, on a daily basis in BK Häcken, entered the penalty area and fell over.
Eleven-meter kick for Sweden and ahead stepped Manchester United professional Anthony Elanga, who forcibly scored 1-0.
Continued forcing
The blue and yellow youngsters then did not slow down, but instead steamed on and got a second goal just before half time.
And it was a beautiful one.
Midfielder Bilal Hussein was responsible for a fine action in the center of the field when he served Wålemark, who coolly pushed in 2-0 behind the Bosnian goalkeeper.
The away nation did not have much to bring and their match was largely characterized by substitutions due to injuries.
Rolled up Bosnia
Sweden was able to continue its forcing and with just over a quarter of regular playing time left, the next roll came.
Tim Prica was responsible for the preparation until the 2-0 shooter Elanga - who showed safety when he shaved the ball into goal.
But it was not over there.
Just minutes later, a pattern attack found its way to Hussein Ali's sensitive right foot and further into Benjamin Nygren, who via the forehead steered the ball into goal.
The match ended 4-0.
Sweden tops the European Championship qualifying group with 14 points.
Just behind is Italy.
The Swedish U21 national team will face Ireland away in the next European Championship qualifier on Tuesday, 18.30.
