Schwarzer became the second oldest player to feature in the competition in Chelsea's 1-0 victory over the Romanian outfit, and the Australian stopper has revealed that it was "huge" for him to play at the highest level of European football.
The 41-year-old told the Daily Mail: "It was huge. My wife always says that I'm unemotional. I'm very German, she says, in that respect but I was elated, after the game especially.
"The manager had faith in me and trusted me and gave me this opportunity to fulfil a lifetime's ambition to play at the highest level, in the Champions League."
Schwarzer has made a combined total of 51 appearances for Middlesbrough and Fulham in the UEFA Cup and Europa League.
