The former Coventry City midfielder has shone when called upon this season.
Pardew said: "If I had to pick out a player who really emerged from the run it would be Gael Bigirimana.
"In terms of a young player who was called upon to do a difficult job, he did really well and announced his arrival here.
"He has not had many chances, but he handled the group stage games and that was a step up for him. Bigi is a great lad and a terrific pro."
