The Brazilian midfielder says he doesn't know what the future holds but insists he is happy with life at the club
The midfielder only arrived at the Volkswagen Arena from Bayern Munich in August, but admitted he doesn't know what the future holds, despite being under contract until 2018.
Speaking to reporters, the 26-year-old said: “If a big club comes, you have to look. It's hard to say what will be in the future."
But Gustavo, who has scored once in 14 Bundesliga games, did add that he was pleased with his start to life at the club, which sees Wolfsburg sit in fifth spot at the time of writing.
“I feel better and better, the club (Wolfsburg) has big goals,” said Gustavo at his side’s Abu Dhabi training camp.
“I’ll give everything until the last day."
Wolfsburg next play against Hannover 96 on January 25 when the Bundesliga resumes.
