Miranda has praised the impact that Adem Ljajic made during Inter Milan's 1-0 victory over Genoa last night.
The Serbian midfielder, who is on loan at Inter from Roma, scored the only goal of the game at the San Siro in the 59th minute.
"The most important thing is for everyone to stay calm," the Brazilian centre-back told the club's official website.
"When you have players like Ljajic, everything becomes that bit easier. When you keep calm, rewards will come and our matches have proven that."
The win lifted Inter to the top of the Serie A standings, one point ahead of Fiorentina.
