The veteran shot-stopper kept yet another clean sheet in his 100th Champions League appearance for the Old Lady
Massimiliano Allegri thinks Gianluigi Buffon proved he is the world's best goalkeeper in Juventus' Champions League semi-final victory over Monaco.
Juve won the away first leg of the tie 2-0 on Wednesday courtesy of a goal in either half from striker Gonzalo Higuain.
But Buffon also played an important role, making five saves en route to a sixth consecutive Champions League clean sheet – a club record – and Allegri hailed the 39-year-old's performance at Stade Louis II.
