Sandro hopes Tottenham can build on their vital victory over Blackburn when they take on Bolton on Wednesday.
Harry Redknapp's side posted their first league win in four attempts in the 2-0 victory over Rovers on Sunday to return to fourth in the table on goal difference.
Sandro, who hit the crossbar early on in the one-sided affair, is refusing to rest on his laurels as Spurs aim for another three points at relegation-threatened Bolton on Wednesday.
The Brazil international told the club's official website: "It was a very good win, and very important because we've lost a few games.
"Now we have to concentrate on the next game and try to get into the Champions League.
"It's another big game, another difficult game. Everyone has to be ready. The last three games are so important for us."
Sandro has yet to score for Spurs this season but feels a goal is coming as Redknapp's side prepare to face the Trotters, Aston Villa and Fulham in their run-in.
He added: "I was close! I will try my best to score in the next three games. It's coming..."
