The Nerazzurri have had a few poor results in the opening weeks of the 2012-13 campaign, but Buffon feels they could go far if they become more consistent under head coach Andrea Stramaccioni.
"Inter have opted for a younger approach and I believe that’s the right way of going about things. If they manage to gain consistency they could be a threat all the way," Buffon told reporters.

"Napoli have a settled system and style of play, along with a first-rate squad.
"Lazio are also having an exceptional season so far. I don’t know their coach [Vladimir Petkovic], but he’s showing himself to be intelligent and capable of moving with the times, as well as speaking our language better than many Italians do."
Nevertheless, Buffon remains confident that Juventus can successfully defend their title this season.
"Our process of growth, which began a year and a half ago, is still continuing. By following a prudent strategy, the directors have strengthened the team during the summer transfer market, so there’s no doubt we’ll be able to fight for the title right until the end of the season."
Juventus currently sit joint first in the Serie A table with 19 points from seven games.
