Guardiola speaks out on Man City for first time (all)
The ban means that as things stand, City cannot qualify for the Champions League in either of the next two seasons.
But the Spanish boss does not think the case is closed, as he believes the team have a chance to appeal the decision.
"It is not finished. The club believes it is unfair so we are going to appeal and we are going to wait," he told Sky Sports after his side's 2-0 win against West Ham on Wednesday.
"So all we can do on the pitch is all we have done in the last four years and try to win games. We are going to wait. I trust my club 100 per cent and what they have done. They have explained to me the reasons why and we are going to see.
"We spoke. We are going to fight, like we fought every single day, until the end of the season. We are optimistic. Next season, if we qualify for the Champions League we will be there.
"If they don't sack me, and that can happen, I will stay here. First because I want to stay, it is something special, beyond the contract I have. I want to stay to continue to help the club and maintain this level as long as possible."
He added: "Why should I leave? I said a month ago, I love this club, I like to be here.
"Why should I leave? We spoke with the players - in the next three months we will focus on what we have to do and after we will see the sentence. Personally, I will be here."
