VfL Wolfsburg star Luiz Gustavo is 'extremely unhappy' at the club, according to his agent.
'Gustavo isn't receiving the respect that he deserves', his agent said. 'He could play for any of the top clubs in Europe.'
The statements come on the back of reports that Barcelona were willing to purchase the defensive midfielder for €28 million.
During a press conference this morning, VfL Wolfsburg boss Dieter Hecking refused to comment on Gustavo's future at the club.
