The veteran goalkeeper is keen to measure himself against top opposition as the Bianconeri have set their sights on a semi-final spot
The Italian champions started the competition as a mere outsider after missing out on Champions League football in the past two seasons, but they have impressed on their way to the quarter-finals as they saw off teams such as Chelsea, Shakhtar Donetsk and Celtic.
"When we started off on our journey that has brought us to where we are today, no-one would have expected us to make such swift progress. But that’s what’s happened and we’ve deserved it," Buffon said at a press conference.
"I don’t know how far off we are from being considered a top team. But this test will tell us a great deal, we’re curious to face it. We’ve got two intense encounters ahead of us and I hope they’re balanced.
"The most important thing is to have no regrets, but I don’t think that will happen. Up until now we’ve always shown maturity when dealing with crucial moments."
Tuesday's first leg is scheduled to kick off at 20:45CET.
