Cyrus Christie believes that he "did well" on his first start for the Republic of Ireland.
The 22-year-old told The Herald: "In training, the manager told me when Seamus [Coleman] said he was struggling, so he just told me to get right and I just prepared as usual as I would if I was starting a normal game.
"He told me [on Friday] before the game that I was going to be starting, so I had my game head on and I was ready and I went out there and I thought I did well. I was lacking a bit of match fitness, I haven't really played that much this season, so for me to step out on the pitch was great, and the team played well.
"I'm a laid-back character, it doesn't really bother me too much. I slept well, I slept as usual, I slept [on Friday] afternoon. I just prepared right and it paid off."
The Republic of Ireland host Georgia on Monday.
