Beretta, who was axed by Lecce on March 9, has stuck up for the man who once mocked him by labelling him "Barnetta."
"I think that he is a good Coach and I also like him a lot as a person," the Milan native told Radio Kiss Kiss.
"It is true that he talks a lot, but I think that's because he is in charge of a big team and he is exposed to the Press more than others.
"And when you are in his position of talking a lot I think it can happen that you exaggerate.
"To be honest I think he says things that many of us would like to say but which have never been said."
