Internacional do not expect Sandro to move to Tottenham until after next season's kickoff.
There are also work permit complications for the youngster, whose transfer was confirmed by Spurs yesterday.
Inter announced that Sandro is due in London this week to undergo a medical but he would not complete a move - reported to be valued between £9-12million - until August, after the Copa Libertadores finishes.
Sandro will not automatically qualify for a work permit because he has played just once for Brazil, in their World Cup qualifier against Chile.
