Juventus are battling Inter to bring in Manchester City full-back Aleksandar Kolarov, valued at £6m.
The Serbian international has repeatedly suggested he wants more playing time and is prepared to leave City in order to get it.
Inter had been tracking the former Lazio man for some time, but according to Tuttosport Juventus are surging into the lead.
They have proposed a €1.5m fee (£1.3m) to take Kolarov on loan for a year, plus an option for another €5.5m (£4.7m) to make the move permanent.
The funds would be raised by selling Swiss international Reto Ziegler to either Galatasaray or Besiktas, as they have reportedly offered €4m.
Juve have already done business with Manchester City this week, signing Carlos Tevez for €9m (£7.7m) plus a further potential €6m (£5m) in performance-related bonuses.
