Lazio chief Igli Tare is preparing to find a replacement for Stefan de Vrij.
The Holland defender is still to settle on terms over a new deal, with his current contract expiring in June.
Corriere di Roma says Porto defender Diego Reyes is under consideration - with his deal also ending at the end of the season.
Mexico international Reyes, 25, is being watched by Tare as a potential successor for De Vrij this term.
De Vrij has fielded interest from Juventus about a Bosman move to Turin.
