Juventus are insisting Chelsea sacrifice young gun Cesare Casadei in talks over Dusan Vlahovic's sale.
Juve are willing to part with the Serbia striker this summer, which has alerted Chelsea and Manchester United.
Juve are demanding 80m to sell Vlahovic - the same amount they paid Fiorentina for the striker 18 months ago.
But Calciomercato.com says Juve are willing to drop their valuation if Chelsea include Casadei in their offer.
The midfielder only moved to Chelsea a year ago from Inter Milan and has just come off a record-breaking U20 World Cup campaign with Italy. He spent last season on-loan with Reading.
