Whilst it was near the end of his career at the top level, Ronaldinho enjoyed an impressive spell with AC Milan under Carlo Ancelotti's stewardship in the 2008/09 season, and with the Italian now unattached the Brazilian has declared a return for the Italian coach would represent a good signing.
Vincenzo Montella remains in charge for the moment, however the club sitting seventh in Serie A is doing the former Fiorentina coach no favours.
Speculation surrounding his position has been rife of late, especially with the gap between the Rossoneri and league leaders, Napoli, already standing at a sizeable nine points.
"Carlo [Ancelotti] is, with Guardiola, one of the greatest coaches in the world," Ronaldinho explained in an interview with La Gazzetta dello Sport.
"It is clear that if the club decides to make a change, the return of Ancelotti would be a good signing.
"He knows the environment and is loved by everyone, especially by his players."
Sunday's derby match with Internazionale is a potentially decisive fixture for Montella as a defeat at the hands of their fierce rivals could force the club's hierarchy into action, especially after a summer of unprecedented spending.
Ronaldinho also believes that he should be given time in the job admitting that a group needs time to adapt to a coach.
"Sometimes when you change coaches so regularly, it is good to give a group time to adjust to a coach and develop a tactical system," he continued.
"Though Montella knows that in certain clubs, especially with a team like Milan, there is often little time."
The nature of the former Real Madrid coach's departure from Bavaria is a little unusual and there have been suggestions that a negative atmosphere within the dressing room is what eventually forced the club to act.
Having worked with the former Chelsea coach for a single season, the former Barcelona forward simply does not buy into that narrative.
"I don't think it was like this [negative atmosphere], Carlo is the number one at creating a genuine, strong understanding with his players," he said.
