Eto'o was sold by Guardiola last summer to Inter, but the Cameroon ace remains on good terms with the coach.
"Nothing and nobody can cancel out what (Jose) Mourinho has achieved at Inter," he told the Gazzetta dello Sport.
"Clearly everyone can take the path they see fit. I don't know if any of my teammates want to leave too, but I intend to stay on at Inter. I am convinced we can win many more titles here."
"It would be a real coup to get him on the bench," said the ex-Blaugrana star.
