Roma have announced the signing of Patrik Schick from Sampdoria on a five-year contract in a move that could be worth an overall €42 million.
Schick, 21, has also been linked with Juventus and Inter Milan this summer but will only join Roma on an initial loan.
In a statement on their official website, the Serie A side broke down the club-record deal for the Czech Republic international striker as "an immediate loan fee of €5 million and, upon the completion of certain sporting objectives, an obligation to make the transfer permanent for a further €9m.
"The terms of the permanent transfer also include various performance-related bonuses, worth up to a maximum of €8m, based on the achievement of certain sporting objectives on the part of both the club and the player.
"Additionally, Sampdoria are entitled to a final payment of €20m in February 2020. Should Schick be sold prior to 1 February 2020, the clubs have agreed that Sampdoria will be entitled to 50% of the eventual transfer fee or €20m -- whichever sum is the greater."

Schick, who arrived in the Italian capital on Monday evening ahead of the move, scored 11 Serie A goals for Samp last season.
"I am very satisfied to be here and very happy," Schick told Roma's 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."
Schick flew in to Turin on June 22 from Czech Republic's under-21 camp while they were participating at the European Under-21 Championship to undergo a Juve medical, with whom he had already reached an agreement.
That move collapsed weeks later when Juve sought a reduction on the €30m they had agreed to pay Sampdoria after a cardiac issue was discovered during tests.
He returned to Sampdoria where further tests were performed and, several weeks later, he was given the all-clear by their doctors to resume training, although he still had his eye on a move.
Inter were reported to be leading the chase, but Francesco Totti, in his new role as Roma director, sent the 21-year-old a message, convincing him to join them.
