Leigh Griffiths has laid an embarrassing pool smackdown on his Hoops buddy Luca Connell .
The Celtic striker, who has been struggling with injury of late, took out his frustrations on the green felt by potting every ball without his opponent managing to sink any.
The embarrassment is palpable on the face of teenager Connell who throws himself onto a nearby sofa in disgust, much to his opponent's glee.
In the background and off camera, someone can be heard to shout: "Grannied. You've been grannied. Embarrassing"
Griffiths looks in fine fettle and proud of his achievement as he spreads his arms to adopt a victorious pose towards his vanquished opponent.
The video was posted on Connell's instagram with the words "What's that 6-1 in games now @leighgriffiths?"
The highly-rated 18-year old arrived at Celtic Park from Bolton in the summer.
