Roma have made no secret of their desire to retain the services of defender Chris Smalling when his loan spell with the club ends in July.
Manchester United have now confirmed their asking price for the 30-year-old.
According to TuttoMercatoWeb, United have now set their valuation of Smalling at €18 million as they look to offload the former England international when the summer transfer market opens.
Since his move to AS Roma in 2019, Smalling has made 22 appearances in all competitions.
