The Argentine has been linked with a move since the end of the season, and in his first public statement admitted the time to leave was now
Corinthians announced on Thursday that negotiations for Montillo had come to an end, after a reported €8.5 million offer was rejected by the Belo Horizonte outfit as insufficient.
However, the 27-year-old released a statement through his press agent the same day affirming that he was keen for a move to go through, although he insisted that he was still happy at Cruzeiro.
"I want to make it clear that previously I have not expressed my desire to leave Cruzeiro. I preferred to stay out of speculation in order to enjoy the holidays and rest with my family. Just yesterday [Wednesday] I met with my agent and I was informed about the official proposal received from Corinthians," the midfielder stated.
"I have always been happy in Cruzeiro, I have a great affection for the fans, but I am 27 and at this time I have to think about what is best for my family.
"I saw yesterday the president's declaration saying that the decision was mine and I believe that I cannot miss this chance."
Montillo arrived in Belo Horizonte in 2010 after a successful spell with Universidad de Chile, and received his first international call-up for Argentina in the past year against a local Brazil team.
