Joao Pedro hopes to start for Watford in tonight's FA Cup replay with Tranmere Rovers.
Pedro was one of several players drafted in for the original third-round tie and the 18-year-old former Fluminense forward looks set to be involved again.
"I was very happy with my debut and felt really comfortable too," Pedro told the club's YouTube channel.
"My team-mates gave me confidence and made me feel at ease.
"Obviously there is always nerves, but after my first bit of play at the beginning of the game, I felt more settled."
Swapping the warmer climes of Rio for chilly Hertfordshire, though, has proved a testing transition.
"In Brazil, the game is a bit slower. Here the game is faster and the space is tighter," Pedro said.
"But the only thing I think I need to get used to is getting used to breathing the cold air, which is something different for me and is really tough."
