Chelsea defender David Luiz could be key to landing Porto ace Hulk.
The Daily Star says Hulk has hinted that he would be keen on a move to Stamford Bridge so that he can join up with old pal David Luiz.
"I am playful and get along well with everyone," the 25-year-old is reported to have told Globoesporte.
"But my companion was David Luiz at Sao Paulo and Vitoria early in my career. He is a great friend and today is a pleasure to play alongside him."
