Connor Goldson
That could be that. Rangers double their lead with the St Johnstone defence all at sea. James Tavernier's initial cross is blocked but his second effort finds the head of Connor Goldson. His effort finds the corner of the net despite Zander Clark getting a touch.

It's that man James Forrest again. The ball breaks to him 10 yards out and his shot is goal-bound until Alan Power gets in the way. Celtic scream for a handball but the referee Greg Aitken blanks the appeals.
St Johnstone 0-1 Rangers
Rangers come within a whisker of doubling their lead as St Johnstone defender Tony Ralston makes a hash of trying to clear a James Tavernier cross and the ball bounces off Alfredo Morelos narrowly wide.
"He's got away with one there," booms BBC Sportsound commentator Rob Maclean.

Quote MessageThere's a lot of nonsense to be said about the role of a modern striker. All any striker has to do is score goals and that's what Alfredo Morelos does.

Celtic 0-0 Kilmarnock
James Forrest is revelling in his role on the left. The winger gets his fourth shot on target of the opening 25 minutes, cutting on to his right foot and letting fly from the edge of the box. Kilmarnock goalkeeper Laurentiu Branescu gets down smartly to save and then block Callum McGregor on the rebound.
St Johnstone 0-1 Rangers
St Johnstone goalkeeper Zander Clark punches a James Tavernier effort clear - you get the feeling that the next goal will be crucial.
The visitors remain a goal to the good, courtesy of Alfredo Morelos's brilliant strike.
Celtic 0-0 Kilmarnock
Boli Bolingoli forces a corner for Celtic as the hosts look to break the deadlock. Kilmarnock, who have looked impressive defensively in the opening 20 minutes, clear their lines.

Image source, SNSQuote MessageMorelos has that in his locker. It's a little self-inflicted by St Johnstone since Tanser didn't cover himself in glory. Jack is brilliant with the breakaway from the corner. Morelos shows strengths and composure to then finish it.
St Johnstone 0-1 Rangers
The hosts spurn a glorious chance to equalise almost immediately. Matty Kennedy's cross gives Alistair McCann the chance to finish but he fluff his lines.
What a start to the second half in Perth.
Alfredo Morelos
We have a goal in Perth and it's a brilliant one at that. Alfredo Morelos wriggles away from the St Johnstone defence and is coolness personified to steer his shot high beyond the helpless Zander Clark

James Forrest comes within a whisker of breaking the deadlock as his effort clips the post on its way out for a goal kick.

We're back under way in Perth.

Quote MessageWhat will give Stevie May confidence is finding the back of the net. It has been such a long time for him. He had a poor spell at Aberdeen by any striker's standards. He needs goals.
Celtic 0-0 Kilmarnock
Another chance for Celtic to break the deadlock as Boli Bolingoli feeds James Forrest but the winger's tame effort is comfortably gathered by man mountain Laurentiu Branescu.
It looked the perfect opportunity for Forrest to hit his trademark outside-of-the-foot flash at goal...
Celtic 0-0 Kilmarnock

Quote MessageThe start Kilmarnock had would have spooked any manager. Especially losing in the Europa League [qualifiers]. The some of the former players coming out and criticising him. But Angelo Alessio has been around the block and he's a professional - he's got them well-organised now.
Celtic 0-0 Kilmarnock
Moritz Bauer concedes possession, allowing Kilmarnock to spring a lightning counter attack. However, Callum McGregor is on the scene to nullify the danger.

Tyrone Smith
BBC Scotland at McDiarmid Park
Not a classic in Perth so far. Have Rangers been the better side? Yes ... but they haven't got into their stride.
Why? Because Saints have been resolute and not allowed it, in a game where chances have been at a premium. In fact, the hosts have really grown in to things as the game has gone on.
Image source, SNSTommy Wright will be hoping for more of the same, but Steven Gerrard will be demanding more from his side after the break.
Celtic 0-0 Kilmarnock
Almost the perfect start for Celtic as Callum McGregor plays the ball into Ryan Christie, who controls before fizzing a shot narrowly wide.
St Johnstone 0-0 Rangers
Billy Dodds
Former Scotland striker on Sportsound
Quote MessageWe've talked about St Johnstone's tactics and how they've grown into the game. What do you do if you're a Rangers player to counter that? Everything is static. Not much movement or angles shown from the forwards. The defenders aren't moving the ball quick enough and the midfielders don't really want it. They have to speed the game up.
St Johnstone 0-0 Rangers
Willie Miller

Quote MessageScott Tanser has been very impressive. I've watched him a lot this season. Great quick feet to get himself to the byline and then a magnificent cross in to the box. Just unlucky that he couldn't find a team-mate.
