Tottenham have left new signing Sandro out of their Champions League squad.
The 21-year-old arrived from Internacional at the start of the month after agreeing a £6m switch in March.
The defensive midfielder, who is considered a future star in his homeland, has declared his desire to help Spurs succeed in their debut Champions League campaign.
Sandro won the Copa Libertadores, South America's premier club competition, in the summer.
But his new club have not registered him in their 25-man squad to play in the Europe's equivalent, which will be a bitter blow to the Brazil international.
