Guardiola has never managed a season without Champions League football and there have been suggestions that he would leave City this summer in the wake of the ruling.
But the 49-year-old, who is contracted to the Etihad Stadium until June 2021, has insisted he will not walk away from the club even if the appeal is thrown out.
He added: “I will stay here. First because I want to stay, it is something special, more than the contract I have.
“I want to stay to continue to help the club. I said a month ago, I love this club, I like to be here. Why should I leave?
