The Manchester City manager has made barbed comments about the Real Madrid manager, saying 'The Special One' is "working well in what he is trying to do" as a coach
There is a perceived feud between the pair that dates back to when Mourinho succeeded Mancini in the Inter job and took the Italian's team to Champions League glory, something the latter has never managed to achieve.
They reacquainted themselves earlier this season as the Portuguese manager's Real Madrid side knocked Manchester City out of the Champions League.
Mancini seems to have ignited the tensions between the pair further with comments regarding the manner in which Mourinho touts himself to the bigger clubs.
"I read one day that Mourinho is going to Paris Saint-Germain. The next day it's Inter, then Manchester City, Manchester United and then Chelsea," he told reporters.
"I am very happy for him. I think he is working well in what he is trying to do."
Mancini followed this facetious quip with a more serious statement of intent as, despite a premature Champions League exit, he remains secure in his role at the club.
"But I don't feel under any pressure at City," he continued.
"I am disappointed we are out of the Champions League, but this is football."
