Andrea Barzagli is expected to meet with Wolfsburg today to ask that an agreement be reached with Juventus.
The 29-year-old has been linked with a move to Turin for weeks and reports in Italy claim he has already agreed personal terms.
However, Wolfsburg are said to be unhappy with the fact Juventus think they can get the player for free when he has six months left on his contract.
Juventus had apparently proposed to reduce one of Wolfsburg's installments for Diego in accordance with the Barzagli deal, but the Bundesliga outfit want cash.
