The Portuguese club's chairman Pinto da Costa will only conduct business in the same manner as the deal that looks set to take Andre Villas-Boas to the Blues on Wednesday
The Portuguese and Europa League champions have already been deprived of coach Andre Villas-Boas, who is about to embark on a new challenge at Chelsea.
Reports in Portugal are suggesting that the Portuguese coach may not travel to the London-based club alone, as he is looking to take midfielder Joao Moutinho and striker Radamel Falcao with him.
Da Costa has refused to rule out selling a number of the club's assets in the summer, but stressed that potential suitors will have to be prepared to meet the player's buyout figures.
"If there are contracts with release clauses, we have to be prepared that some player might want to leave if the stipulated figure is met," he said.
"But I will not go to any country to negotiate.
"Just like it happened with Andre Villas-Boas, there will be no talks: there is an account number and money deposited there."
The Porto president added he is unaware of Chelsea's interest in one of his club's players, saying: "We have not had any contact about the transfer of players and we do not know the intention of any one of them to leave."
