Saul Niguez's early goal proved the matchwinner as Atletico won 1-0 the first-leg of their Champions League round of 16 tie in Madrid.
At the final whistle, Simeone remarked: "It was the game we expected, with a very strong opponent, with different records on their field and ours, and I think we responded very well at the start and then we played as we had to play.
"Even on some occasions we could have increased the advantage.
"If the attackers and midfielders had not participated in the defensive work, the defenders would not have been so good."
On the atmosphere at the Wanda Metropolitano, Simeone added: "In eight years I have not seen such an ovation."
On the second-leg, he concluded: "We are going to play with humility, because they are used to playing great games in their stadium."
