Former Barcelona defender Marlon is delighted with his move to Sassuolo.
Barca retain a buy-back option in the deal, though Marlon now sees his future in Italy.
"I'm very happy to be at his club. I'm grateful to everyone for the trust they've placed in me. I want to show my worth as soon as possible," he said.
"A lot of Brazilian defenders have been successful in Serie A."
Marlon mentioned that Thiago Silva and Sergio Ramos are two players he admires the most in the game.
"One day I'd like to reach their level," he added.
