Interim boss John Kennedy claimed referee Willie Collum denied Celtic a clear-cut penalty in their 1-1 draw with champions Rangers at Parkhead.

Hoops attacker Mohamed Elyounoussi headed in an Odsonne Edouard cross in the 23rd minute of the Scottish Premiership encounter but minutes later the French forward was booked for diving in the box after a challenge by Gers defender Borna Barisic.

Colombia striker Alfredo Morelos levelled in the 38th minute with his first goal against Celtic and, although the home side had the best of the game, Steven Gerrard's men made it 33 league games unbeaten to keep the 20-point gap between the teams intact.

Kennedy said of the penalty claim: "It had a massive say in the game. I’ve seen it back and I’ve spoken to Odsonne.

"If you get any sort of contact in the box, when a player comes flying at you at that speed, comes recklessly in, knocks you off balance, touches you enough to go over – that’s what happened there.

"If he doesn’t go over, he is on the ball, he scores the goal.

"There is no need for him to go down, he is a goal scorer, he wants as many goals as possible. He is not that type of player.

"I haven’t had a chance to speak to the referee. In games like that, these decisions are massive, really important.

"Willie will have his opinion on it, other people might think differently but we are sure it’s a penalty.

"So we feel aggrieved that we didn’t get a penalty kick, we have to accept that and look at the bigger picture of the performance which was good.

"It was a high level performance. I thought we were dominant most of the game and scored a really great goal, which we were pleased with and disappointed with the goal we conceded. Overall pleased, and the attitude was terrific.

Brown was praised for his gesture before the match

The Celtic players put Old Firm rivalries aside before the game. Rangers players had decided not to take the knee before kick-off in support of Gers midfielder Glen Kamara and the Celtic players did likewise.

The Finland international claimed he had been subject to a racist slur by Ondrej Kudela during the Europe League defeat by Slavia Prague at Ibrox on Thursday night.

Celtic skipper Scott Brown had a quick word with Kamara in the build-up and substitutes, management and backroom staff of both clubs stood along the touchline in a show of solidarity.

Former Celtic defender Kennedy said: "It is important. This is not about derbies, rivalry, opposition.

"This is about unity coming together, and trying to make a difference.

"It has gone on too long. It seems to happen more and more even though there is more education.

"It is not acceptable. You give someone, or whoever it may be, a punishment for it and that will quickly eradicate it."

Rangers manager Steven Gerrard echoed these sentiments after the game.

"I thought it was a class touch from both clubs, everyone standing up and showing the support and getting behind it.

"So fair play to both clubs, it was really pleasing to see.

"I thought he (Glen) was faultless today, I thought he was really good.

"He gave exactly what we wanted him to give. He battled well, he passed it well and he helped us get a positive results so I am really pleased for Glen, he will go away now with his national team and focus on that.

"I thought it was a good game, I thought it was all set and ready for one team to grab it. I think the result suits us both, we are away from home.

"We have had a tough journey in term of physically and emotionally over the last couple of weeks and we are already champions. So this results suits us.

"We came here to win, if we can't win, it is important we don't lose and take the point and move on."
