Dundee United 1 Celtic 4: Landmark night for Griffiths as champions stroll

Leigh Griffiths broke through the 50-goal barrier for Celtic with a brace as the Scottish Premiership champions cruised to a 4-1 win at rock bottom Dundee United.

Former Wolves striker Griffiths capitalised on a slip from Gavin Gunning and thumped a 21st-minute goal through home goalkeeper Eiji Kawashima to bring up the landmark – removing his jersey to reveal a shirt bearing the number 50.

That act of exuberance earned the goalscorer a yellow card, but he and his team-mates were celebrating again six minutes later as Jozo Simunovic dispatched a close-range header from Kris Commons' left-wing free-kick.

United briefly rallied and pulled a goal back before half-time, Simon Murray converting John Souttar's throughball, but it was 3-1 early in the second period as Griffiths swivelled at the far post to steer home and Commons volleyed a wonderful fourth in the 56th minute.
