In an interview with Koeln’s Express he denied that a deal had been struck with the reigning German champions.
"The speculation over a move to Bayern has no basis. There has been no request from Bayern and no contact. To talk about an agreement is nonsense," Tonnies explained.
"We are not interested in selling a key player like Rafinha," he added.
Contrary to the Koenigsblauen’s denials, the Munich Abendzeitung are reporting that the Bavarians have actually come to an agreement with the 23-year-old Brazilian.
The newspaper claims to be quoting sources in the Schalke leadership. Rafinha has a contract at the Veltins Arena until 2011 and a transfer fee of a few million Euros is being mentioned.
While there is doubt over the Rafinha story, one thing is clear - Bayern will be looking to strengthen their defensive line. Philipp Lahm is guaranteed a place, but Willy Sagnol has retired, while both Christian Lell and Massimo Oddo have failed to convince.
Although Rafinha is a key player at Schalke, he has also provided for a number of negative headlines in recent times.
He went AWOL during the summer Olympics against the club’s wishes and has has incurred the wrath of his neighbours with some late night parties.
