If you're going to make a list of things to achieve on your debut, scoring is right up there and Derryman Shane Duffy has made a memorable first appearance for Celtic.
After completing his year-long loan from Brighton, the Irish international has now opened his account for the Scottish champions with a thumping header against Ross County.

After taking an early lead when Odsonne Edouard slotted away a penalty, Neil Lennon's men doubled their advantage thanks to a goal from Albian Ajeti.
Duggy's commanding header in the 59th minute made the points assured for the Bhoys and they've since added a fourth goal thanks to Kristoffer Ajer.
As things stand, Celtic remain in third place, six points behind leaders Rangers, but with two games in hand to play.
As for Duffy, we've a feeling that we'll be seeing him score plenty more goals like this one.
Take a look.
