"He should be 85 for finishing because he's such a special finisher," said Walker-Peters.
The 23-year-old provided the assist for Ings' first goal in last month's 5-2 defeat to Tottenham Hotspur and says it's the striker's practice in training that makes him so clinical.
"Every opportunity he gets to strike the ball on goal in training, he takes it seriously," Walker-Peters says.
"He doesn't get bored and try fancy finishes. It's always the same finish. It's that practice that makes him so clinical."
