Roma have made a first offer to Manchester United for Chris Smalling.
Smalling is currently on-loan at Roma, though no permanent option was included.
Roma have now opened talks with United about a fee for the defender.
A first offer of €10m has been tabled - only half of the Red Devils' asking price at a reported €20m.
Giallorosso sporting director Gianluca Petrachi says Smalling is welcome to tie down a deal at the Stadio Olimpico in Rome.
"If Smalling wants to remain here, we will discuss this with United," he said. "The relationship between the two clubs is great and if there are any possibilities, we are going to consider it."
