Kroos netted with a magnificent free-kick in the dying embers of the clash in Sochi, salvaging a 2-1 win for the defending champions whose hopes of progressing from Group F would have taken a significant blow without the late intervention.
However, ugly scenes between the two sets of coaches unfolded on the touchline after the final whistle, with the officials forced to intervene.
And, when asked to give his version of events in his post-match news conference, Andersson did not hold back in criticising the Germany coaching team.
"Some of the German coaches celebrated by running in our direction, rubbing it into our faces by making gestures, and that really got me annoyed and angry," he said.
"There were many people on our bench who were very annoyed.
"We fought it out for 95 minutes and when the final whistle goes you [should] shake hands and leave, so I was very angry with that."
However, Germany head coach Joachim Low said he did not see his players or staff making gestures towards the Sweden bench.
"He told reporters: "I didn't witness that because after the final whistle we concentrated on other things."We fell into each other's arms, my assistant coach and I. We were elated, over the moon really.
"I didn't see any gestures towards the Swedish bench at all."
Victory over South Korea will likely make sure of Germany's place in the last 16, but a draw or a defeat could see the defending champions eliminated, while Sweden now likely need a victory over Mexico to make sure of their place in the knockouts.
