Max Allegri praised the likes of Gianluigi Buffon and Dani Alves, but remains "angry" with playmaker Miralem Pjanic after Juventus' 2-0 Champions League semifinal away win at Monaco on Wednesday.

Two goals from Gonzalo Higuain, both set up by Brazilian wing-back Alves, gave Serie A table-toppers Juve the upper hand in the race for a spot in the Champions League final.

The principality club were held to nil at the Stade Louis II for the first time in Europe this season but Allegri knows Leonardo Jardim's men travel well, as evidenced by their recent display in Dortmund.

After praising his Bianconeri players, he urged caution ahead of the return leg in Turin.

"The boys played a great game. They defended very well. It's not easy, because Monaco have a great attack, very fast players going forward," Allegri said after the match.
