Cruzeiro have told Manchester United to make a huge offer if they want to sign their star midfielder Everton Ribeiro.
The Red Devils were linked with an €8m move for the 24-year-old as David Moyes looks to strengthen his options in midfield after a disappointing start to life as manager of Manchester United.
But Cruzeiro's president Gilvan de Pinho Tavares was quoted by Terra saying it would take a much bigger bid to see the player leave for Old Trafford.
He said: "A lot of money will be needed to buy him. I can't say no for life, if the bid comes to what I want. But I'm good when keeping players. I kept Montillo for an entire year, so the fans can relax, because not any bid will take Everton."
The news will come as a blow to Moyes who has under four weeks to revamp a Manchester United squad that has failed to mount a title defence the season after Sir Alex Ferguson retired.
Manchester United have so far lost five times at Old Trafford in all competitions this season and a lack of quality in midfield has been mooted as a possible reason.
It will also be bad news for the player himself, who in November admitted his desire to join United ahead of Real Madrid.
"I will continue doing my job here at Cruzeiro but plan on getting to a big club," he told Brazilian TV. "It's a dream I've had since young, I've always liked Manchester United."
