The Denmark international scored the winner against Bournemouth at the weekend, and Spurs face a showdown with the European champions in the Bernabeu tomorrow (7.45pm).
Eriksen knows what it’s like to take on Los Blancos, having played them twice with Ajax during the Champions League group stage in 2012.
Ajax lost both ties 4-1 but five years on, Eriksen believes Spurs are equipped to do better.
"You need quality and belief. I think we have both so I don't think we should be scared of anything," he told Sky Sports.
"I haven't won there yet so I need to change something. Of course it's a special stadium, a special place.
"Playing against Real will always be special for any footballer with the history they have and the players there so it will be a good test, to see how far we've really come."
Tottenham have taken maximum points from their opening two Champions League group games against Borussia Dortmund and Apoel Nicosia.
But Eriksen says Spurs, on the back of third and second-place finishes in the Premier League, have shown they can go toe-to-toe with the best.
"I think we've shown it in the Premier League," he continued.
“Overall with the consistency over the last two seasons, we've definitely proved that we are a team that will hopefully have a very nice and very tough game at the Bernabeu.”
Eriksen's goal against Bournemouth extended a superb start to the season for the midfielder, who now has four goals in his last five matches for club and country.
"Of course nobody wants to be called a one-man team," Eriksen said in reference to Pep Guardiola’s comments about Harry Kane.
"I think over the last few seasons it's been almost the same team every season. We know each other very well.
"There are strong links between all the players and a good feeling going into training and going into the games.
"We've got something special and I hope that's what people on the outside see, and it's what the squad feels."
