The pair appeared to ignore each other when the centre-back was substituted on Saturday but the Italian has denied a rift despite his annoyance at his appearance for Belgium
The centre-back captained his country to a 1-0 World Cup qualification victory over Macedonia and was publicly criticised by the City boss for choosing to play for his country soon after recovering from a calf problem.
Mancini and Kompany then appeared to ignore each other when the 26-year-old was substituted during City's 4-0 victory against to Newcastle on Saturday.
Asked if the two have spoken since the disagreement, Mancini told reporters: "No, for what? Vinny knows that his behaviour was not good."
The former Inter manager denied, however, a rift between the pair after reports had claimed that Kompany had not reacted well to Mancini's comments to the media.
Asked why they appeared to ignore each other as Kompany left the field, Mancini said: "I was happy because he played well. Kompany didn't have any problem."
