Spurs face the Italian giants in the Champions League and Redknapp insists his team will attack.
“We always have a go; we play an attacking game,” he said. “We’ll look to have a go tomorrow and try to cause them problems.
“We won’t just look to sit back and soak up pressure for 90 minutes; that’s not the way we play.
“We’ll be positive and see what we can do.
“Obviously, he (Van der Vaart) changes the way we play. We played one system when Rafa was playing and it suited him fine.
“He’s not here but the other players can play the same type of role.
“Luka Modric is a world-class player, so he could easily slot into that same role that Rafa plays.”
“We feel as though we could give anybody a game – so we’re ready.”
