Jose in hot water again after outburst
The outspoken Portuguese, whose team are closing in on a fourth straight Serie A title, has had a number of run-ins with coaches and soccer authorities this season after being appointed at Inter in June.
"It surprises me how he has this knowledge. It doesn't seem very elegant or educated," Napoli coach Roberto Donadoni told Sky on Monday.
"He probably wanted to fire off one of his usual phrases. I don't see the motivation or the necessity."
Napoli president Aurelio De Laurentiis has sat with Donadoni on the bench since appointing the former Italy coach to succeed Edy Reja earlier this month.
"Mourinho's comments were pathetic," Cagliari coach Massimiliano Allegri added. "There was a lack of respect."
The former Chelsea coach has bemoaned the media grilling he receives in Serie A and some vague comments about his future have sparked speculation his stay in Italy will be short.
