The Real Madrid defender was delighted with the result in the semifinal first leg and paid tribute to Iker Casillas for his late save on Mario Gotze.
Carlo Ancelotti's men held off the European champions' attacking threat at Santiago Bernabeu, with the visitors failing to convert their possession into meaningful chances as Karim Benzema's early goal settled the Champions League semifinal first leg.
Ramos, 28, believes Madrid did well to get the one-goal win and praised goalkeeper Iker Casillas for his late save to deny Roten substitute Maro Gotze an equalizer.
"We worked hard, it was an intense game," Ramos told reporters after the match. "We put in a great defensive game.
"We didn't hand them possession, they are a great side. With this support at the Bernabeu it makes everything easier though. We're used to super saves with Casillas now! He's such a good goalkeeper. We'll go to Munich humbly, with this good result, but with hope."
Real Madrid lost 2-0 when it was in Germany earlier this month and edged past Borussia Dortmund in the quarterfinals 3-2 on aggregate.
