The club are reportedly on the brink of receiving a two-window transfer ban.
Speaking before Saturday's FA Cup quarter-final with Swansea City, Guardiola said: "I cannot say something every press conference. I was clear in my opinion.
"The club have made their statement. I'm not giving any comments. I'm not even the right guy to talk about that.
"The club do it, then call me and tell me what they are doing."
