The wing-back is not impressed with the Allianz Arena side's defensive options, and has singled out Arjen Robben and Franck Ribery as their main attacking threats
The left-back, who was under contract with Juve from 2005 until 2010, has warned his former team the Bundesliga leaders always try to play their own game, but feels Bayern's lack of quality at the back opens opportunities for the Bianconeri which they could exploit.
"Bayern always try and play their own game, but they are not exceptional in defence, in particular at centre-back," Molinaro told Tuttosport.
"Dante is having a great season, but the problem is who will play alongside him. At the moment Jupp Heynckes opts for Daniel Van Buyten, and that's Bayern's most vulnerable spot.
"He is not a fast player and he could suffer against [Mirko] Vucinic and [Sebastian] Giovinco."
Molinaro then went on to single out Franck Ribery and Arjen Robben as Bayern's main attacking threats.
He added: "Ribery is very unpredictable. However, I would also keep a close eye on Robben. Many think that he will not play, but I believe he will."
The first leg of the tie takes place at the Allianz Arena on April 2.
