Brazilian defender Roger Ibanez da Silva has joined Roma from Serie A rivals Atalanta on an 18-month loan deal which includes an obligation to buy, both Italian clubs said on Monday.

Roma confirmed the transfer was worth 10 million euros ($11 million) including bonuses, with the final purchase depending on the 21-year-old meeting certain targets after the loan period which runs until June 30, 2024.

"Roma has everything I want in a club - it's a huge side. I am certain that I will be happy here," said Ibanez who joined Atalanta in January 2019 from Fluminense, but featured just twice.

His most recent appearance was as a substitute in the decisive Champions League group-stage win over Shakhtar Donetsk in December which put the Bergamo side through to the last 16.

Roma and Atalanta are fighting for top-tier European football next season and are fourth and fifth respectively in the Serie A table.
