Confidence is understandable as we meet just three days after Tottenham's famous win at Manchester United. This was a game in which Spurs seemed to shed their former selves, playing with a bravery not all sides of theirs have shown at Old Trafford. It was a new assurance which Sandro revels in, and which he put down to the manager, Andre Villas-Boas.
"Before the game we had spoken a lot about this, about how a lot of teams go to Old Trafford and the moment overcomes them and they are overwhelmed. But the instruction, particularly from the manager, was: 'Go out there and play your normal game. It's a game of football.'
"There was a lot of talk in the build-up about the history of this fixture, how it had been so many years since Tottenham won. But we all went out on to the pitch with this in our minds: 'seize the moment, play the game, win the game, nothing to fear'."
Sandro is obviously enjoying the Villas-Boas era, and believes he is taking Spurs forward. "It is clear tactically that our manager is one of the best. We all knew that from his history before he joined the club and what he has achieved and every day we are learning tactically, as you can see from the recent performances. Especially we are very well prepared for every match.
"It helps all the players a great deal that the manager speaks perfect English, perfect Spanish, Portuguese, French, and so everybody understands very clearly the message. Personally, it is a big help that the manager speaks to me in Portuguese. When I first joined the club, I didn't speak any English and it was difficult to fully understand, even with the help of people translating for me, exactly what the messages were at times. It was frustrating.
"The big difference now is especially during a game, if there is a 30-second break, I can go over to the substitutes' bench to get a direct message from the manager, if he wants me to do something differently or pass on a message to one of the other players, I can now understand and react in the moment.
"I've got a good relationship with him, I'm very much enjoying working with him. He is one of the best out there, not just for me but for all of the team. And it helps that if there is something that is not going right we can approach him, or he can come and speak to us.
