The City captain incurred the wrath of Mancini after Kompany represented Belgium in a World Cup qualifier despite a two-month spell on the sidelines at the Eastlands outfit.
The Italian, who was sacked in May, publicly criticised his centre-half but the 26-year-old is adamant he has always been fully committed to City’s cause.
“You are injured, you are out, you lose. There is nothing you can say that will make it good. That is why I did not say too much about it,” said Kompany.
“I think the most important is that I feel good now. I have always been committed to my club. Everybody knows it over there.”
Asked whether his relationship with Mancini was strained towards the end of the manager’s reign, Kompany added: “No, I think out of experience you have different managers and different styles.
“There is not one manager who can say he knows it all. Even the best managers in the world have deficiencies. You learn from every manager.
“I have learned a certain way from Wilmots, I have learned from Mancini and I learned from [former Manchester City boss] Mark Hughes. I have concentrated on the positives.”
