Son told Sky Sports News that Spurs are relishing the fixture and are "hungry" ahead of the last-16 second leg.
"We are hungry; we are not finished," the South Korean said. "It's a Champions League game against a difficult opponent. We play at home but we are not scared. We need to play our game, be confident and play forward like we play at Wembley. That's the most important thing.
"We are looking forward to playing against a good team, a good opponent. I hope it's a great atmosphere and I think we have a great opportunity. You can see how well Tottenham play. We deserve to play in the Champions League to the quarter-final or even more.
"We are good enough. If we win, everyone will be proud of Tottenham. I have to accept it if the gaffer doesn't choose me: I just have to be ready if I come on or if I'm on the bench."
