Hoffenheim expect Roberto Firmino to leave Bundesliga this summer
Brazil international Roberto Firmino is set to leave the Bundesliga this summer, Hoffenheim CEO Peter Rettig believes.
Firmino, 23, has become a regular in the Brazil squad under new coach Carlos Dunga after not being called up by former Selecao boss Luiz Felipe Scolari for the 2014 World Cup hosts last summer.
The attacking midfielder has been linked with a move away from Hoffenheim, who finished the season in eighth position and outside the European qualification places.
Firmino's agent Roger Wittman said in March that the player was set to leave the club this summer "should Hoffenheim agree a transfer fee with a club."
The midfielder was linked with Bundesliga rivals Borussia Dortmund and Schalke, though the duo are believed to no longer be in the market for him after failing to reach their goals this season.
His name has also been mentioned in relation to Bayern Munich, but speaking to Bild, Hoffenheim CEO Rettig said that he thinks the Brazil international will end his time in Germany after 140 appearances for the Kraichgau-based club.
"I don't rule out that he'll stay at Hoffenheim, and I also don't rule out that he'll stay in Bundesliga. But basically you have to expect a transfer abroad," he told the paper.
When asked about the potential transfer fee, Rettig said anything from €30 million upwards "is not unrealistic," but added that so far no clubs have made a move for Firmino.
"Robert has turned into a top player here," he said. "He became a Brazil international. But I am not aware of any offer. We'll have to wait and see."
Firmino has been linked with several Premier League clubs in the past, with Sport Bild in March reporting that Liverpool, Arsenal, Chelsea and Manchester United were all monitoring the midfielder.
Chelsea midfielder Oscar has praised his compatriot Firmino, telling Squawka that the 23-year-old "has a great future ahead of him."
