Bigirimana is expected to feature against Metalist Kharkiv tomorrow night.
"Europe is an opportunity for us as young players and it is up to me to work as hard as I can to be involved," said the 19-year-old, who joined from Coventry City in the summer.
"I have signed a big, long contract (five years) but I'm still young so I am just trying to learn and improve every day.
"Now it is up to the manager but I am here if he needs me.
"The Premier League is very important but we want to win the Europa League and, with the new players, our squad has a lot of options so it is what we are all aiming for."
