A heated quarrel broke out between Lagerbäck and Leipzig star Alexander Sørloth during the Norwegian football masters' latest gathering.
The striker was dissatisfied with the Norwegian tactics in the European Championship playoff match against Serbia, which Norway lost 1-2, which later made the Swedish national team captain roar away.
"After 30 years in international football, I have never experienced a player cross the border in this way," said Lagerbäck in a statement on the Norwegian Football Association's website.
Despite the quarrel, the 24-year-old is also in Lagerbäck's squad for the next three international matches.
- We agreed to put the matter behind us.
We will not communicate this to the outside world anymore.
We have put an end, Lagerbäck said in connection with Monday's squad presentation, the news agency NTB states.
Leaks in the squad
He also took the opportunity to air his irritation against the leaks that are obviously in the national team.
- For me, the national team is for professional players, amateurs are those who leak things that do not benefit the team, said Lagerbäck, according to VG.
Lagerbäck also sent a hefty scoop of criticism of the media's reporting on the matter, and specifically pointed out the newspaper VG.
- Based on isolated events that took place that evening, interpretations and speculations have been made that do not agree with how I experienced the situation.
