The goalkeeper was in superb form as the Italian side kept a clean sheet against the free-scoring Ligue 1 team in the Champions League semi-final
Monaco coach Leonardo Jardim felt Juventus goalkeeper Gianluigi Buffon was the difference in the first leg of their Champions League semi-final.
Goals in either half from Gonzalo Higuain saw Juve record a 2-0 win at the Stade Louis II on Wednesday.
But Buffon, 39, was instrumental for the Serie A champions, making numerous saves to put them in control of the tie.
Jardim's team have been prolific this season, but were unable to get past Juve and Buffon, and the Monaco coach said the shot-stopper was key.
