ALAN HUTTON believes Steven Gerrard's 'tactical genius' and an 'outstanding' performance from Glen Kamara were key to Rangers' Old Firm win on Saturday.

The Gers moved four points clear at the top of the Premiership as Connor Goldson netted in either half to clinch a comfortable derby victory.

On a day where there were plenty of positives for Gerrard, the performance of midfielder Kamara was one of the main ones as he produced a superb showing against Celtic.

And former Ibrox star Hutton reckons the Finnish international was integral to the way the game unfolded as full-back Jeremie Frimpong was isolated out of the encounter.

Hutton told Football Insider: “Absolutely outstanding. This is a guy who’s kind of flew under the radar for a little while and I think his recent performances at international level and then bringing that into the Rangers team, he was actually pivotal to what Rangers were doing.

“He was stopping the flying wing-backs of Celtic going forward. He nullified Frimpong, he hardly touched the ball and it was all to do with Kamara spotting the danger, he could see what was happening, what was building up and he’s got the energy to get all over the pitch.

“He was the one that would go out and stop Frimpong attacking. He did his job absolutely unbelievable – Frimpong is the danger man for them and he did basically nothing in the game.

“It was really a bit of tactical genius from Gerrard to use Kamara’s energy up and down the pitch to stop one of their main threats on the day.”
