Porto president Pinto da Costa doesn't want to lose striker Hulk this month.

Hulk's agent encouraged Chelsea to open talks with Porto over a fee for the striker, whose contract carries a €100 million buyout clause.

"I hope that no-one meets Hulk's buy-out clause, but I would not be surprised if someone pays €100m some day," he told Jornal de Noticias.

"I would like, however, that no-one paid that figure."
