Wolfsburg's Grafite is hoping in-demand strike partner Edin Dzeko resists the urge to jump ship in the summer.
The talented Bosnian striker, who was heavily linked with AC Milan last season, eventually stayed and signed a new contract.
However, the rumour mill has continued with the 23-year-old tipped to leave for a bigger club in the summer.
Dzeko's Brazilian strike partner Grafite is not taking any notice of the speculation and believes his colleague should stay if he is happy.
"Personally I do not believe these rumours," he told Kicker.
"Big clubs are on his tail but it is also very important for him to be happy.
"That is why I really hope to see him stay on at our club."
Grafite is an outside bet to make Brazil's World Cup squad in South Africa although he is not holding his breath on making Dunga's final 23.
"I don't have a big chance. I'm not kidding myself, my chances are extremely small," he continued.
"I'll be doing my very best to make the World Cup squad, but I'm thinking more about Wolfsburg, my club."
