Juve are well placed to win their third successive Serie A title, sitting eight points clear of second-placed Roma with seven matches to play.
They lost just their second league match of the season last week, slipping up 2-0 at Napoli - a result that ended a 22-match unbeaten streak in Serie A.
Antonio Conte's men are currently trying to negotiate their way through a tricky period, with the club's UEFA Europa League commitments often seeing them play three times a week, and their packed fixture list has led to several injury problems.
Striker Carlos Tevez - the leading scorer in Serie A - is Juve's latest concern after he asked to be substituted with thigh pain in the club's 1-0 win at Lyon in the first leg of their Europa League quarter-final on Thursday.
The injury problems have seen some of the club's squad players given regular game time, one of whom, Martin Caceres, has impressed greatly.
Caceres has replaced Barzagli with aplomb at the heart of Juve's defence and was particularly solid in the club's win at Lyon.
"He's a permanent fixture for Uruguay and the only thing that's kept him out of the side is Barzagli's magnificent form," Bonucci told Juventus' official website.
"He's showed he has what it takes to play for Juve.
"He's a superb man-marker, very good at beating his man to the ball. He's perfectly at ease slotting into this back three."
Domenico Di Carlo's side trailed by two goals at the break but produced an excellent comeback as goals from Paulinho and Innocent Emeghara saw them claim a point.
