Juventus coach Massimiliano Allegri has praised the character of his charges following their Champions League last-16 comeback win over Tottenham Hotspur at Wembley.

The Old Lady sealed progression into the quarter-finals thanks to quick second-half goals from Gonzalo Higuain and Paulo Dybala, which cancelled out a first-half opener from Son Heung-min to earn Juve a 4-3 aggregate win over Spurs.

"The changes made a difference and gave us a real boost, it was the right time because I felt there had been a bit of dip in the physicality of the Spurs players," Allegri told reporters after the game.

"Even at 1-0 down we had a good reaction and we carried on playing, we knew we were capable of scoring and if anything we were concerned that we would concede another goal.

"You are going to find certain games that are really tough. We did suffer, but that's normal in football. We worked on possession a great deal and that was important to us."

Juventus now return to Serie A action when they face Udinese on Sunday afternoon.
