Atletico Madrid president Enrique Cerezo has told Sergio Aguero he will not be sold this summer despite going public with his desire to leave.
Aguero, 22, posted a statement on his website saying he felt he needed a move to continue his development - despite having signed a new contract until summer 2014 as recently as January.
Cerezo, though, told Radio Marca: "We are not going to change our thinking. We will not sell or trade for Aguero. If anyone wants to know something new, ask him directly.
"There is no getting around it. El Kun has a signed contract. He has shown his desire to leave, but we say the same thing. We do not want to sell.
"We respect his decision, but he also has to respect ours. He has a commitment to us.
"In his recent statements I heard him say he had no intention of leaving. I do not know how we will address this issue, but this is not the end of the world."
Aguero has been linked with a move to city rivals Real Madrid as well as a switch to Serie A.
Cerezo added: "We do not know where he wants to go, but we can say that there has never been an official contact with another club."
Aguero's statement on Monday read: "I said long ago that when I wanted to go, I would say so publicly. And the time has come.
"So I keep to my word and here I am. I find it hard to leave Atletico. It hurts and saddens me.
"I've thought long and hard and I am convinced that I must be true to myself."
Los Rojiblancos' vice-captain claimed he signed the new deal with an understanding that he may leave this summer, merely wanting to ensure Atletico received a larger fee.
"I want to say also that this decision has been maturing for some time," he said.
"The issue was discussed and agreed with Atletico last year when I was renewing my contract."
Aguero has scored over 100 goals for Atletico since joining from Independiente as a teenager in 2006.
