Hulk cannot rule out a move away from Porto.
Manchester City, Manchester United and Tottenham have all been linked with the Brazilian striker.
"If a transfer appears good for all parties then we should consider it," he said. "There is always a lot of speculation about me but it does not bother me at all.
"The important thing is to concentrate on Porto and do my job. I'm already at a big club. Since arriving in Portugal I have improved a lot but I can still play a lot better."
