Gianluigi Buffon insists Juventus must up their game to succeed in the Uefa Champions League this season.
The Bianconeri have returned to the competition after not participating for a few years and, having landed the Serie A title in an unbeaten campaign last term, expect to have a major impact on the tournament.
However, a draw on Tuesday night against FC Nordsjaelland has dented their hopes of progress. Shakhtar Donetsk have taken control of Group E to leave Buffon and his side fighting it out with reigning champions Chelsea to make the last 16 teams.
"It's a difficult competition. I said to my companions, 'what we do in Italy and Europe is not enough'," the Italian World Cup winner told fans via a video conference.
"[To qualify for] the second round we must play against Chelsea. I knew it would be tough after the draw in the group.
Speaking briefly of his plans after football, the goalkeeper was non-committal: "I do not know [what I'll do]. I need projects, I always need challenges, I always need to win races. My life has always been like this since I was a kid."
