It was after today's match against Tingsryd (loss 3-2 after penalties) that Wallson announced his decision.
So it is tough criticism and a harsh tone on social media that made Wallson make the decision.
"This has affected Walle hard and also his family, which means that Walle chooses to step down from his assignment with immediate effect.
This was not something we had planned for, but we accept Walle's decision and we directly dissociate ourselves from personal attacks ", says CEO Blomberg on the website and develops the reasoning.
"It is unfortunate that this has gone so far.
We will now try to make the best of the situation to support Walle and be able to enter the playoffs well prepared. "
The club is looking for a replacement for Wallson and some contacts have already been made.
