Juventus goalkeeper Gianluigi Buffon has backed his side to recover from their poor start to the season.
Juve have made their worst start to a season since 1912, losing their first two league matches, and are one of five sides without a point at the foot of the table.
But Buffon told Sky Sport Italia: "These are actually the challenges which bring the best out of me.
"It's great -- fantastic in fact -- to be at the start of a new cycle. Changes are good for you because they give you even more motivation.
"Whenever you've got to get your hands dirty, work hard and reinvent yourself, then I really enjoy myself. I've always given that bit more when there has been a difficult challenge.
"It can all be remedied, I'm sure. I'm not concerned."
The arrival of Hernanes from Inter on deadline day should help, with coach Massimiliano Allegri getting the playmaker he had been searching for since losing Andrea Pirlo and Arturo Vidal.
"I'm now aware and mature -- I'm in the prime of my career," Hernanes said at a news conference in Turin.
The 30-year-old said he felt "stronger than ever before," and added: "My age has given me the experience, and I will get the chance to show my value here.
"I'm going to have many great things to experience here, starting with the Champions League, which I can't wait to play in."
Hernanes could make his Juve debut when they host Chievo next Saturday, with their opening Champions League fixture coming against Manchester City three days later.
