Bundesliga outfit Wolfsburg have completed the capture of Brazilian full-back Fagner, while rivals Werder Bremen have played down links to Srdan Lakic.
Fagner has penned a contract with Wolfsburg which will run until June 2016.
Reports in Germany suggest the 23-year-old arrives in a £2.5million deal from Vasco de Gama.
Fagner has prior experience of life in European football from a short spell at Dutch side PSV Eindhoven, but will be hoping to fare considerably better second time around.
"It has been pretty obvious that we were out to clinch one more player for this role on the pitch," Wolfsburg manager Felix Magath told the club's official website.
"Fagner is an attacking right-sided full-back. He plays the role in a way that I like best."
Fagner added: "I am delighted to be at Wolfsburg and to have the chance to perform in a competition of the quality of the Bundesliga.
"My goal is to be a regular in the line-up of this club and to help them achieve the best position possible in the league."
Meanwhile, Werder Bremen have sought distance themselves from reports suggesting they are planning a raid for Wolfsburg striker Lakic.
The Croatia international ended last season on loan at Hoffenheim, but he is back with his parent employers and hoping to force his way back into first-team contention.
"We had looked into the case of Srdan Lakic, but that is all," Bremen's general manager Klaus Allofs told Kicker-Sportmagazin.
"A transfer of Srdan Lakic is not an option at this point in time."
