Roma have completed the signing of forward Patrik Schick from Sampdoria on loan with an obligation to buy for a club-record fee.
The 21-year-old Czech Republic international scored 11 Serie A goals last term, and had agreed a move to Juventus before issues in his medical saw the deal fall through.
The Giallorossi have disclosed details of a structured deal which sees them pay an initial €5million loan fee, before a further €9m to make it permanent on a contract running until 2022 should unspecified sporting objectives be fulfilled.
Roma have agreed to shell out a further €20m in 2020 and could also have to make additional performance-based payments of up to €8m to Samp.
"I am very satisfied to be here and very happy," Schick told the club's official website. "For me Roma is the ideal team.

Roma sporting director Monchi added: "Patrik is one of the brightest prospects in international football.
"We are all very satisfied to agree this deal especially because, despite being chased by a number of clubs, he has chosen us."
