Newcastle boss Pardew enthuses: Bigirimana should be playing for U21s
Bigirimana, who grew up in war-torn Burundi and lived in Uganda before following his mother to England in 2004, signed from Coventry City in July.
"I don't think he's ready though and he shouldn't be playing in this team if I'm honest," said Pardew.
"He should be playing in our under-21 team, but we are in such a place that he gets an opportunity and you would like to think that he will take that.
"He did more than that - it was a fantastic goal and something he will treasure for the rest of his life."
