Madrid - Barcelona said Thursday they have reached an agreement with Sassuolo to transfer their Brazilian defender Marlon Santos to the Italian Serie A side for €6 million.
The Catalan giants retain the right to buy back the player, and will keep 50 percent of the economic rights on any future sale of the 22-year-old, the club said in a statement.
"The clause regarding future sale will not come into effect if Marlon plays 50 games with US Sassuolo Calcio, at which point the Italian club is obliged to pay another €6 million," it added.
Santos joined Barcelona from Brazilian side Fluminense on loan in 2016, before completing a permanent deal a year later.
He spent the 2017/18 season on loan at French side Nice, making 26 appearances.
