The Juventus shot-stopper feels that Serie A is becoming more competitive again having seen clubs bolster their squads on the transfer market
The Bianconeri have triumphed in the last two campaigns in Italy, though the veteran shot-stopper believes that there are plenty of contenders who have strengthened their squads in the past couple of months.
Buffon highlighted Napoli and Fiorentina in particular, though also refused to rule out the threat of AC Milan and Inter, who endured differing fates in Serie A in the previous campaign.
"Our league is improving," Buffon told the club's official website. "Napoli and Fiorentina have been playing good football for a year, made spectacular progress and I think the players who have chosen to play in Italy have also come to this conclusion.
"Napoli have bolstered their squad and recruited a winner as their coach. He’s someone I have a great deal of respect for, a great professional who knows what’s required in order to win.
"Fiorentina also have the signing of Giuseppe Rossi, who if he clicks with Mario Gomez will form part of an international level strikeforce.
"Milan are competitive even without making big statements in the transfer market, because they’ve already got players that allow them to be amongst the front runners.
"Inter’s best signing has been their coach and they already have a foundation of six or seven young and important players. They’ll soon be able to get back to winning ways."
