Walter Mazzarri looks set to be unveiled as Napoli boss after what president Aurelio De Laurentiis described as a busy day.

The future of Roberto Donadoni has looked tenuous all day after De Laurentiis said the club had "different ideas".

De Laurentiis also spent much of the afternoon in talks with Gian Paolo Montali, a Juventus board member and former volleyball coach who is tipped to become the club's new general manager.

De Laurentiis told his club's website, www.sscnapoli.it, this evening: "The fans can rest easy because I'm working for their future.

"It was a busy day, long, full of events and interviews.

"As soon as I can I'll communicate the decisions for the good of Napoli."

De Laurentiis is also thought to have spoken to Sampdoria director Giuseppe Marotta, as Mazzarri is still contracted by the club he left at the end of last season.

Sampdoria lost 2-1 at Roma yesterday to drop to 15th in the Serie A standings.

The result marked Napoli's fourth defeat of the campaign and has put further pressure on under-fire coach Donadoni.

"I adore Donadoni as a person, he is a true gentleman," said De Laurentiis after the Roma defeat.

"But probably we have different ideas."

Napoli parted company with general director Pierpaolo Marino last week and Donadoni looks certain to be next to be shown the door.

The former Italy tactician has struggled to make an impact since taking charge of the Naples outfit in March, posting just four wins in 17 matches.

Moreover, Napoli have not won on the road since beating Lazio 1-0 in October.

"I have made my first move, and other ones will follow in the next three or four months," said De Laurentiis.

"We shall see whether among those decisions there will be a coaching change.

"I have all the time in the world."

Former Lazio coach Delio Rossi and ex-Inter Milan boss Roberto Mancini had also been linked with the post.
