The 35-year-old midfielder has spent the last nine seasons in Serie A with Atalanta, making more appearances for the club than any other player in its history with 445 outings across all competitions. De Roon's contract situation has allowed Roma to move quickly to secure a low-cost deal, with the transfer bringing a reunion at Roma with his long-term Atalanta head coach Gian Piero Gasperini.

De Roon has been spotted arriving at the airport in the Italian capital and is now expected to have his medical and contract signing before being officially announced as a new Giallorossi player. A specific price tag for De Roon has not been mentioned, but given his age and contract situation, it is likely to be a nominal fee.
