"Seven minutes to go at the Swissporarena 1-1 FC Luzern v St Johnstone..."

'Well double their lead and it's the debutant at the deadly double! Josh Law is at his predatory best as he flicks the ball over the advancing Jonsson.

"Josh Law makes his competitive debut for Motherwell against Stjarnan, following in the footsteps of his brother Nicky.

"He will hope to not see at first-hand one of the crazy goal celebrations that brought the Icelandic club to the attention of the football world when they became popular on YouTube."
