A report has emerged in the media, suggesting that Manchester City falsified many of their sponsorship deals through their owners.
It is said in the German magazine Der Spiegel that City's Abu Dhabi owners were the ones who funded many of the sponsorship deals to ensure City met FFP requirements.
"I think about that issue, the club made a statement last week about what happens about stolen mails," Guardiola said in his press conference when he was asked about the issue.
"What I can say is I trust a lot with the club about what they have done. And, of course, we want to follow the rules of UEFA, FIFA and the Premier League.
"They [the club] do what we have to do. Believe me, I am completely honest, I don't know what happened [regarding the Football Leaks allegations] because I am a manager focused on the pitch and the locker room.
"How they handle this situation, I am completely out of that. But I am part of the club. I support, absolutely, the club. And we want to do what we have to do in terms of the rules.
"If it undermines what we have done or not, opinions are free in those terms. In the end, focusing on what we have to do on the pitch is all we can do."
