Sandro's proposed move to Tottenham looks to be off after Internacional stated he would not be leaving this month.
Spurs have been chasing the 20-year-old since last summer and he was expected to move to White Hart Lane during the current transfer window.
But problems appear to have arisen over a proposed link-up between the two clubs.
"Sandro is not moving in this transfer window," Inter's vice-president Fernando Carvalho told Radio Gaucho.
"The partnership with Tottenham has not been finalised, there are a number of details which we did not sign up to.
"Sandro's exit could only have happened if this was in place.
"He will now play in the Libertadores for Inter, it may come in August that he will move to Europe - but that could be true of any of our players."
Sandro's agent Luiz Chignoli also denied reports in England that he had agreed terms with Spurs over the move.
"It is not true," he insisted.
"The English press has invented that Sandro has had medicals in England too."
