The Wigan striker has become the subject of an unlikely hit
"Will Grigg's on fire! Your defence is terrified".
It's a chant that has become more popular than it ever should have, and looks like it won't be stopping any time soon.
Grigg has played seven times for Northern Ireland, but has yet to score. The Wigan striker looks to be one of the players at risk of missing out on the 23-man squad.
BBC Sport NI got some of the players to sing the chant as Will Grigg-mania continues to spread. You have to commend Roy Carroll's refusal to take part in the video. The 38-year-old clearly knows where his priorities lie.
