Juventus goalkeeper Gigi Buffon feels they've proved their Champions League credentials this season.

Juve need to avoid defeat Shakhtar Donetsk to qualify for the knockout phase.

Buffon said: "Over the last four or five months, in which we've faced both Serie A and Champions League fixtures, I think we can safely say that the Juventus growth process has been consolidated.

"Regardless of how things go tomorrow, I think taking on a tough group and winning the games we did shows that this team has everything it needs to provoke fear in our opponents.

"Aside from the result, which obviously is fundamental for us, Juve are giving off the impression they have returned to being competitive on a European level.

"Can Juventus win the Champions League? My view is that dreaming costs nothing, but it's also true we have to be realistic. There are undoubtedly three or four stronger teams out there for various reasons, but as I said three months ago before our first game at Stamford Bridge, we can give anyone a game."
