Barcelona vice-president Javier Faus has hit out at their 14-month transfer ban.
Barca have announced they're appealing the ruling.
Faus blasted: "What's happening is not a coincidence or accidental.
"We will investigate who is behind this and when we can prove it, we will comment.
"There are many people who cannot stomach the fact that the club wins everything and has been at the top of football for ten years. They can't take it, but we will not stand here with our arms folded and the response will be forceful. I can guarantee you that.
"I'm surprised that Barcelona's training model is being called into question. La Masía has always set an example. We are absolutely against all of this. We are optimistic after speaking to the lawyers. We hope that FIFA rules on our side."
