Why do they take so much time to reach a decision? But it is not like Ibrahimovic hid his involvement with Bethard. He was quite vocal about his involvement with that company and was even announced as their brand ambassador back in 2018.
The likelihood he will get suspended is relatively small. His lawyers definitely checked the situation beforehand and even a Swedish soccer official said the rules are unclear, implying that they had a thorough look at them in advance.
