Ex-Fifa official: Referee made major blunder as Celtic jersey footage analysed

Celtic should not have been allowed to wear their grey third kit in their 2-0 defeat to St Mirren on Sunday (18 September), according to Keith Hackett.

Speaking exclusively to Football Insider, the ex-Fifa and Premier League referee insisted the kit clash made life “difficult” for the assistant referees.

St Mirren wore their traditional black and white striped home kit while Ange Postecoglou’s side lined up in their grey third kit.

The traditional green and white hooped home strip and black away shirt may also have clashed with the Buddies’ kit.

The clash came into focus when St Mirren’s second goal caused controversy.

Jonah Ayunga headed home from close range but Celtic felt that he might have been offside and that he fouled Stephen Welsh in the build-up.

As shown on the BBC’s Sportscene programme, the ball fell to Ayunga after Curtis Main headed down after a long throw.

Asked for his verdict on the kit clash, Hackett said after analysing the footage with Football Insider correspondent Connor Whitley: “It is difficult.

“If it is difficult for you, it is difficult for the assistant referee.

“These two kits don’t make it for me. They needed a different colour.”

Despite their defeat at St Mirren Park, Celtic have gone into the international break two points clear of Rangers at the top of the Scottish Premiership.

They are next in action next month (1 October) when they host Motherwell who have not won a league game since August.
