Napoli president Aurelio de Laurentiis has taken a new swipe at former coach Roberto Donadoni.

After their draw with Parma, De Laurentiis again questioned the work of the former Italy coach.

"An enthusiastic first half was followed by a second that was distinctly below par. The team needs a kind of athletic preparation so it can bear playing an entire game," De Laurentiis explained.

"The fact two strikers had to be substituted because they were fatigued does not convince me. It means to say that whoever was before (Walter) Mazzarri and his staff did not work well."
