Celtic manager Brendan Rodgers last night took aim at the officials who sent off Olivier Ntcham last night as the Hoops were held to a 0-0 draw against St Mirren.

The French midfielder was sent off for a first-half foul on Stephen McGinn, his second booking of the evening, but it was a decision that left Rodgers irked.

And the Celtic manager was unequivocal with his criticism of what he felt was a lamentable performance from referee Andrew Dallas and his match assistants.

Asked how he felt the officials performed, Rodgers said: “Not very good, to be honest.

“I never like to focus too much on the referees but I think for both teams I didn’t think any of the four officials were very good.

“I don’t know if it’s a mark of all the attention that’s around them.

“But there were lots of incidents the got wrong.

“The sending off for me is not a yellow card.

“If you watch it again, the first one is a booking and we take that. But before the second one there is an incident when Olivier makes contact with the ball and wins the ball, but the referee gives a free-kick against us.

“Then when you see it in the corner Olivier is running across to block the ball up the line and he St Mirren player as he plays it is falling over. At the same time Olivier slides but doesn’t have contact with the player.

“So from that – and the fact it;’s in the corner makes it lively – then the ref falls for it and he gets a second yellow.

“For me it wasn’t a second yellow or a sending off.

“I don’t think there was a good one between them all this evening. Listen, it’s simple I don’t think they were good."

The SFA and referees have been in the eye of a storm given decisions that have been made in games this season, something that Rodgers believes speaks for itself in terms of the standard on offer.

“I think the fact we are speaking about them let’s people see there’s been indecision," said Rodgers.

“There’s been a spotlight on the refs and I don’t want to increase that.

“But yeah – it was just a poor demonstration of officiating.

“There were a few. I thought Tom Rogic fouled the St Mirren player but he got on the ball and ran away.

“Then Tom got booked for something ridiculous."

And Rodgers believes that even with ten men Celtic still looked the more likely team to score.

“I will focus on the team and think, ok with 10 v 11 how can we change it?" he said.

“We put all the risk into the game, we put a winger to right-back, put another striker in and played 4-3-2 and tried to do everything to win the game, but we didn’t.”

Meanwhile, Rodgers has praised the news that Leigh Griffiths has tied up his long-term future to the club.

The striker penned a new deal with the club yesterday much to the delight of the Hoops boss.

“It’s brilliant for the club and him and he can get to a level of fitness and availability and hopefully back tos coring goals.

“The supporters love him and we all love him.”
