Guardiola fears the impact of Manchester City's proposed Champions League ban as well as the spiralling costs for players will hinder his summer transfer plans.
Asked by Sky Sports News whether he expects this summer to be as busy on the transfer front as his first summer at City, Guardiola said: "I don't think so. I don't think so because today it is so difficult to change the players because they are so expensive and it is not easy.
"The club must [also] be sustainable, I understand completely and in the situation that we are in we have to wait [not] anticipate. Our idea right now with the situation with Financial Fair Play [is] when we are going to appeal.
"Right now we have to wait. So we are going to play these three months and when the season finishes we will see what the situation is. And with the club, together, we are going to decide what is best - not just for the next year, but for the next two, three, four years for the club."
