Genoa have announced the likely departure of Rafinha less than a year after his arrival at Marassi.
The Brazilian was signed for €9m by the Rossoblu after impressing in Germany with Schalke 04.
"The player prefers the German championship to the Italian championship," Genoa President Enrico Preziosi told Radio Radio.
"He wants to go back to Germany and he confirmed as much in a recent interview too. I think we'll reach an agreement with a big Bundesliga outfit."
The South American, who last year was linked with Milan and Juventus, was recently paired with a switch to Lazio.
