Kris Boyd has slammed Celtic manager Brendan Rodgers, questioning why the former Liverpool and Leicester boss returned to the club.

The Rangers hero pointed to the Scottish champions being worse off compared to this time last season in terms of both points and goals.

Celtic remained top of the league by three points thanks to a late penalty from Adam Idah at Easter Road against Hibernian on Wednesday night.

But Boyd feels the result is simply papering over cracks. Writing in his Scottish Sun column, he said: "I was expecting the 2016/17 version of Rodgers to return and take Celtic by storm again.

"Instead, the Parkhead punters are seeing a very different boss, as Wednesday’s woeful display against Hibs showed.

"Sure, Celtic won the game thanks to two penalties and it could end up being a vital three points.

Yes, they remain top and could go on to beat an improving Rangers team to the title.

"But as I said on Sky Sports, the result was a robbery. And judging by the reaction, that Easter Road performance has only made Celtic fans more worried that Philippe Clement’s side are going to topple them.

"It’s clear something isn’t right at the club. There has been too much of a drop-off from last year’s Treble-winning team.

"They’re nine points and 21 goals worse off than they were after 25 Premiership games last season.

"But that doesn’t begin to tell the story of a season that has raised so many questions about Rodgers’ return.

The former Scotland international has also been left puzzled over what the Celtic board said to the 50-year-old to convince him to return.

"When [Ange] Postecoglou first left for Tottenham, the Northern Irishman privately made it clear he wasn’t interested," he continued.

"What happened to convince him a second stint there was a good idea is anybody’s guess."

"Exactly what vision Dermot Desmond and the Celtic board sold him, I don’t know — but it surely wasn’t this," he continued.

"Watching Rodgers and Celtic this season has been like seeing a couple give a failed marriage one last go.

"It didn’t work out in the end the first time, and the second time is turning out to be a mistake.

"Win or lose the title, it seems inevitable the reunion won’t last long-term.

He went for the full Ronny Roar at Easter Road on Wednesday and relief was etched all over his face.

"I’m struggling to remember seeing him like that during his long career as a boss. Rodgers knew how big a win that was for his team — and himself.

"The Hoops punters, who have been directing their anger to the boardroom instead of the dugout, were on the verge of turning on him, big time."
