The Court of Arbitration for Sport will on Monday announce its findings from City's appeal over atwo-year ban and €30m fine handed down by UEFA for violating Financial Fair Play regulations.
The result will likely have huge ramifications for City, and Guardiola is positive about his club's innocence.
Asked if he would be able to sleep ahead of the ruling, the Catalan told reporters: "I'm going to sleep because I can't do anything [about the verdict]. I would love to do something but I can't.
"I'm confident in the club, I know the defence and their argument. We have to wait, I know there are many clubs in the Premier League waiting too, but we are going to wait.
"It was issued a long time ago, maybe 90 per cent of the people on the pitch and backroom staff were not there [at the club], but we will see and respect the decisions.
"I feel fully confident in what the club has done and allowed us to play in the Champions League next season."
