Roma have completed the signing of forward Patrik Schick from Sampdoria on loan with an obligation to buy.
The 21-year-old Czech Republic international scored 11 Serie A goals last term and had been linked with moves to Juventus and Inter before agreeing to join Roma.
The Giallorossi have disclosed details of a structured deal which sees them pay an initial EUR5million loan fee, before a further EUR9m to make it permanent on a contract running until 2022 should unspecified sporting objectives be fulfilled.
Roma have agreed to shell out a further EUR20m in 2020 and could also have to make additional performance-based payments of up to EUR8m 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.
"I am looking forward to training with the group and getting ready for the upcoming games."
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."
