Juventus goalkeeper Gigi Buffon admits their success under coach Massimiliano Allegri seems "unthinkable".

Allegri has taken Juve to a new level since succeeding Antonio Conte.

Buffon said: "The real quality of this group and the club's DNA is fighting hard. We had lost it for a while, but over the last three and a half years we have reconstructed that mentality and belief.

"As for the Coach, I can only say he has been a very pleasant surprise and he made the most courageous choice a tactician could make.

"To come to Juventus after three historic years, aware he had everything to lose and risk, then get these extraordinary results... you can only tip your hat to him."
