Cruzeiro forward Kleber has said that he does not want to answer any more questions about a possible move to Liverpool with his club insisting that they want to keep him.
The 25-year-old has been persistently linked with a move to Anfield for the 2009/10 season.
"I don't want to talk about this anymore. It's getting boring. If I play badly in a couple of days, the fans will start saying I want to quit," he said to Radio Globo BH. "If I had an offer and if it's profitable for both me and Cruzeiro, my agent (Giuseppe Dioguardi) and (club president) Zeze (Perrella) will try to sort it out."
Club spokesman Guilherme Mendes said that Kleber will not leave the Mineirao for less than 15million euros.
Kleber was signed by the Belo Horizonte side from Dynamo Kiev earlier this year in a swap deal for forward Guilherme which saw the Ukrainian side pay an additional 5million euros.
Mendes said: "Firstly, Cruzeiro have no interest in negotiating for forward Kleber. He was signed and inked a long-term contract with the club and Cruzeiro expect he will win a number of titles in our shirt.
"Neither Cruzeiro nor the player's agent have been made an offer from any European club at this time. There have only been discussions between the player's agent and Zeze about what would happen if a 7million euro offer was made.
"Cruzeiro told him that the club would not discuss any offers of less than 15million euros."
Kleber has scored 19 goals in 21 appearances for Cruzeiro.
