Hoffenheim star Roberto Firmino has played down talk of a summer move to Manchester United.

Firmino is contracted to the German outfit until 2017, but it is believed that he will leave for a bigger challenge after becoming a regular in Dunga's Brazil team.

However, the playmaker has been quick to refute suggestions of an agreement with United, adding that he's only concentrating on his football for the time being.

Firmino explained: "I have a contract with Hoffenheim until 2017 and I'm fine here. I grew up a lot with this club. Now I just think about Hoffenheim."
