"We have only trained a few times together, but we are professionals," the former France international told UEFA.com ahead of the game in North-West Germany.
"We have to communicate a lot and we will do our best to perform as well as we did in Munich. Everyone speaks English in Germany so communicating is not a problem.
"I remember some good games against Tottenham, and they have improved and are now one of the best teams in one of the best leagues. They deserve to be playing in the Champions League. Tottenham have a lot of experienced players.
"Peter Crouch is likely to lead the line for Tottenham and he is very dangerous in the air. He is always in the right place at the right time. You can compare him to David Trezeguet in that regard."
Like Tottenham, Werder had to come through the Champions League qualifiers last month before clinching their place in the group stages alongside Europe's elite clubs and, despite only being at the club for a few months, Silvestre remains bullish about his team's chances.
"There are no easy games in the Champions League but we can beat anyone and teams have a lot of respect for Werder Bremen," he continued.
"I have played a lot of games in this competition and I'm used to it and I have complete faith in my colleagues. They are very experienced and we can handle the pressure."
