Marcelo refused to dwell on his return to action in Real Madrid's win over Osasuna, stressing that his side must now focus on their Champions League semi-final with Bayern Munich.
Los Blancos cut Atletico Madrid's lead at the top of La Liga to three points with a 4-0 victory on Saturday, with two goals from Cristiano Ronaldo and strikes from Sergio Ramos and Daniel Carvajal comfortably seeing off Los Rojillos.
Marcelo expressed his satisfaction with Madrid's three points but was keen to shift the attention from the domestic campaign to Tuesday's clash with the German champions.
"We are good. We now have to rest and think in the important game on Tuesday," the Brazilian told reporters after the game.
"The next game is always the most important and that's how I see it. We have a chance to go through. We have to go into the game relaxed, with humility and respect for the opponent. We will see what happens and if the trees burn or not."
The 25-year-old defender made his first start since suffering a hamstring injury three days after his side's 5-0 win over Rayo Vallecano at the end of March and spoke of his excitement a making a swift return to action.
"I was eager to return," he continued. "I wanted to help the side and, thanks to God, the physios and doctors that have helped me and ensured I'm 100 per cent. When I’m available to help the side and the boss doesn't pick me it's normal I'm not happy and I want to play. The manager decides and I was to play as many games as I possibly can."
Marcelo was also keen to pay tribute to Tito Vilanova after the former Barcelona boss passed away on Friday.
"It was a great shame. He was an example to football," said the left-back. "I want to send a big hug to his friends and family."
