"Alex Sandro would be a great signing for Juventus. He is a classic Brazilian full-back. He has a fine technique and a drive forward. He reminds me of Roberto Carlos a bit," Dunga was quoted as saying by Tuttosport.
"I know him pretty well and have already called him up for Brazil in the past. I keep a close eye on all candidates for the national team, including Alex Sandro.
"He has developed well at Porto. He has improved since his time at Santos. He is capable of sending in good crosses for the attackers, but is also strong in his positioning. He is a typical Brazilian left-back.
"He is similar to Roberto Carlos, especially at a technical level and when you look at their dribbling skills. Alex Sandro is a bit less physical, though. He is not as powerful as Roberto Carlos was."
