Juventus aren't the only Serie A side tracking Gary Cahill, as Inter also show interest in the Bolton and England defender.
The centre-back is already hot property on the Premier League transfer market after Tottenham's bid was rejected.
Spurs will try again in January, especially as his contract expires in June 2012.
Juve had been linked in the last few weeks, but the 25-year-old is now a main target for Inter as well.
New Coach Claudio Ranieri has pin-pointed the centre-back as a valuable addition to his ageing squad.
It is believed the Nerazzurri would offer around €12m for Cahill.
