Manchester United midfielder Michael Carrick acknowledges nights like this Tuesday are the ones that really get his competitive juices flowing.
After almost seven years at Old Trafford, Carrick has enough experience not to be overwhelmed by the biggest of occasions. But he accepts certain matches are beyond the norm. And Tuesday's home encounter with Real Madrid, in the second leg of their Champions League last-16 tie, certainly counts as that.
"These are the nights you live for," he said.
"It is extra special. There is just something in the air. Everyone comes to the stadium with a spring in their step. Every supporter is that little bit more vocal. They appreciate how important it is and what it means to get through.
"The prestige and history of the club suggests we should be challenging in the later stages of these tournaments. It is up to us to go out there and do it."
Iker Casillas' presence in the 24-man Real Madrid squad that flew into Manchester on Sunday night underlines the importance being placed on the game by Jose Mourinho given the vastly experienced goalkeeper has been missing since January, when he fractured his hand against Valencia, and only returned to training on Thursday.
Yet Sir Alex Ferguson's love of European combat means United will be fully primed for a task that includes stopping former Red Devil Cristiano Ronaldo, who returns to his old club for the first time since his Â£80million move to Spain in 2009.
"Cristiano pretty much has everything," Carrick said. "He can shoot with both feet. He can cross with both feet. His ability on the ball is exceptional. He can manoeuvre the ball and generate space for himself, and we saw in the first leg how good he is in the air. You just have defend as best you can, work as a unit and help each other out."
Though a goalless draw will be enough to send United through after last month's 1-1 draw at the Bernabeu, Ferguson has ruled out the potential for such a scoreline given the strength of both teams lies in their offensive potential. It is not an assessment Carrick wishes to dispute.
"Look at both teams," he said. "We both attack well and have all the threats that can create and score at any given time. That is the nature of the tie. Even though you might be defending well, you can never switch off. We had chances in the first leg and so did they. Either team could have won 2-1 or 3-1. It is going to be about who takes their chances on the night."
