Wolfsburg have firmed up their interest in Bayern Munich midfielder Luiz Gustavo with an official approach for the player.
Talking to German newspaper Bild, Wolfsburg director of sport Klaus Allofs said: "We've made contact and expressed our interest. We want to do things correctly. There are still some obstacles to overcome, however."
Gustavo’s opportunities for first-team football at Bundesliga champions Bayern look to be limited by the summer arrivals of Mario Gotze from Borussia Dortmund and Thiago Alcantara from Barcelona. He has not featured during new coach Pep Guardiola’s pre-season plans so far.
Gustavo, who has two years to run on his current deal, was reported as saying: "I have a contract until 2015 and want to see it out."
