Lazio want to reserve an option to buy Davide Zappacosta in any deal to sign the defender on loan this month, but Chelsea want to include a mandatory purchase option.
Zappacosta has played just 18 minutes of Premier League football this season and has been reduced to being a bit part player at Chelsea under Maurizio Sarri.
The Italian wants to leave the club in January and he has emerged as Lazio’s top target in the winter window as the Serie A outfit look to bring in a full-back for their squad.
The Roman club have been in talks with Chelsea and are even prepared to take up 100 per cent of the defender’s wages during his loan stint, but disagreements exist between the two clubs.
According to Italian outlet Tutto Mercato, Lazio only want to reserve an option to make the move permanent at the end of the season, but Chelsea want a more permanent solution.
The west London club want Lazio to agree to an obligatory purchase option in order to guarantee a transfer fee going forward.
Lazio and Chelsea have continued to hold talks over Zappacosta but the two clubs are still some way away from reaching an agreement.
The Italian club believe that by agreeing to pay his wages in full, they have done their bit to grease the wheels for the potential deal and want Chelsea to adjust their demands.
