Mino Raiola says a three-month transfer ban place on him by the Italian Football Association is the product of an administrative error.
The superagent, whose clients include Manchester United's Paul Pogba and Sergio Romero, is unable to broker deals until August 9 in light of the ruling.
The Italian FA did not disclose the reasons behind the ban in a statement issued on Thursday, but Raiola has hit back by claiming the decision was erroneous and says he 'doesn't know what is going on'.
"I immediately called in lawyers and I appeal," the 51-year-old Dutch-Italian national told the Dutch outlet Eindhoven Daglbad.
"This is a personal error. I have not received any explanation.
"Perhaps this is a result of a story from some frustrated weirdo. Write that down. You can ask me three thousand questions about it, but I honestly don’t know what is going on."

Raiola is said to be engineering a move away from Old Trafford for Pogba amid United's failure to qualify for next season's Champions League.
Real Madrid manager Zinedine Zidane was effusive in his praise for the midfielder in March, and Pogba said it would be 'a dream' to play at the Santiago Bernabeu.
Pogba remains United's record signing after his £89 million move from Juventus in the summer of 2016, and Raiola stressed that his ban was only in effect in the Italian market.
"It is a suspension, but only for the Italian market," he added. "And we are challenging that suspension.”
