Spurs dominated the opening proceedings against Anderlecht last week, but they fell to a 2-1 defeat against the Belgian outfit, as they appeared to switch off.
And Eriksen says that defeat has ensured that Spurs will not relent in matches from now on, as they proved at the weekend - when they beat Bournemouth 5-1.
“Anderlecht woke us up and everyone was angry after that game at the way we lost, but it’s good to show straight away that we’re capable of doing better," he said.
“We showed our spirit as a team as well. After the first 10 minutes when there were a few long balls, we got it down and played our football.
“I’m feeling really good and confident at the moment but that goes for all the team – we’re playing with confidence and we want to play forward.”
Spurs' win over Bournemouth was impressive, as they could have crumbled after falling behind in the first minute.
The pressure was on Tottenham to win the fixture after their defeat to Anderlecht in midweek, but they responded with a hat-trick from Harry Kane and goals from Mousa Dembele and Erik Lamela providing them with the victory.
Spurs are now unbeaten in nine Premier League matches, and they are proving to be very hard for any side in England to beat.
Mauricio Pochettino's side have the best defensive record in the top-flight, and they currently are just three points away from the Champions League qualification spots.
