The experienced goalkeeper has yet to add the European Cup to his trophy cabinet and is eager for European success before hanging up his gloves
The Serie A champions made it to the quarter-finals of European club football's elite competition last season, where eventual winners Bayern Munich proved to be too strong, and the Bianconeri skipper is eager to go all the way this campaign.
"Winning the Scudetto is obviously something that never stops satisfying you, but there's no denying that the Champions League is something else. It is not a competition you win easily," Buffon told TG1.
"I already got to the Champions League final in 2003 and I really did not enjoy the experience of losing.
"What would I give to win the Champions League? Let's say I have six or seven years left to play, I'd happily give three or four years of my career to win it."
The draw for the Champions League group stages takes place in Monaco on August 29.
