Juventus are locked in Porto talks for Rolando.
The defender, who spent time on-loan with Inter Milan last season, is keen to return to Italy this month.
Porto won't stand in his way and are now negotiating terms with Juve.
TMW says Juve have offered €500,000 for a six-month loan with the option to sign Rolando permanently for €4.5 million.
Porto are demanding Juve agree to an 'obligated' permanent option, though everything will depend on the will of the player.
