In an interview with
Sportske Novosti, picked up by
Mundo Deportivo, Mandzukic said that he now preferred to avoid any contact with his former boss.
"Guardiola disappointed me -- he did not treat me with respect," Mandzukic said. "He did not let me become the top scorer in the Bundesliga. For me things were twice as good when Jupp Heynckes was in charge.
"Would I sit down with [Guardiola] to have a cup of coffee? That is not going to happen. In my professional life I do not have to like everyone, but when I feel negative energy with someone I try and avoid that person."
Mandzukic, who scored 33 Bundesliga goals in 54 games for Bayern, added: "I did not deserve to be treated as I was, after giving everything for Bayern for two seasons.
"I felt that things changed for me as soon as [Guardiola] arrived. I made an effort to adapt, but it needs both sides to do something for that to happen. I realised that I had no future at Bayern, so I resigned myself to leaving the club and had to choose a new destination."
