"I told them [the president and his directors] I was going 6,000km away and asked them to leave me in peace, but they haven't kept their word," he said. "I did my time [at Barcelona] then decided to leave.
"I want them to get on with the job and I wish them all the success in the world, because their success will also be mine - I don't need to say what I feel for this club."
Guardiola revealed he had been incensed by the suggestion that he had not made the effort to see Tito Vilanova, his former assistant, when the current Barca coach had travelled to New York for cancer treatment.
"Too many things have happened that have crossed the line," Guardiola told the media in Lake Garda, where Bayern are holding a pre-season training camp. "I will never forget that they used Tito's illness to cause me damage, because it's a lie that I never saw him in New York.
"I saw him once, and the reason I didn't see him more often was because it wasn't possible, and that wasn't my fault. To say that I don't wish the best of someone who was my colleague for so many years is very bad taste, and I didn't expect that."
