Moussa Dembele scored a hat-trick as Celtic thrashed city rivals Rangers in their first league meeting since the Ibrox side were liquidated and started life again in the Third Division.
The former Fulham striker first rose above a ball-watching Rangers defence to head home from a corner, then he pounced on a poor pass from Rob Kiernan to fire past Foderingham in the Rangers goal.
Rangers striker Joe Garner pulled a goal back before the half time break. Scott Sinclair fired home Celtic’s third of the game in off the post after being set up by Dembele.
The Ibrox side were reduced to ten men after new signing Philippe Senderos thought he was playing in a basketball game and blocked the ball from looping over his head with his hand. The Swiss player’s departure signalled the end of any hope the visitors had in getting back into the game and Celtic made their one man advantage count.
The 20-year-old Dembele completed his hat-trick after latching onto a cross from Mikael Lustig to fire past a flailing Joey Barton – who was now playing in the centre of defence – and Foderingham. Substitute Stuart Armstrong completed the rout with Celtic’s fifth.
Dembele’s hat-trick was the first in a Glasgow derby since Stevie Chalmers scored one in 1966, with his performance silencing those detractors who thought Celtic would struggle without the services of the injured Leigh Griffiths.
Celtic now sit four points clear of Rangers at the top of the league, with Brendan Rodgers’ side still having a game in hand. Hearts leapfrogged the Ibrox side into second place with a 3-1 win over Hamilton Accies at Tynecastle.
The Scottish champions now travel to the Nou Camp on Tuesday night to face La Liga giants Barcelona in their opening Champions League group game.
