Vieira said: “We sit down with players and they say 'president, I can earn five million euros, president, do not make me stay here.'
“Joao Felix had a release clause of 60million euros and we realised after two or three games that we must increase it to 120million euros.
“But it is Joao Felix and his family who will decide if he stays.
“If someone bids 120million euros it is not worth dreaming that he will stay.
“We are trying everything to ensure he stays. But the only way is if we sell him and keep him another year.
“If not, Joao leaves. There is no room to negotiate further. He doesn't want to. How will Benfica negotiate with someone after he is given a proposal of 6million euros after tax?"
