Over their past 135 minutes of football, Rangers have accumulated an expected goals rating of 5.75.

They have scored just once from that, a goal that was gifted to them by Motherwell keeper Alex Paulsen.

Sebastian Tounekti's trickery gets him clear on Celtic's left but his pass across the box does not find a team-mate and then Haissem Hassan fouls a St Johnstone defender.

Jacob Chapman collects a scruffy attempt from Nicolas Raskin and the half-time whistle blows with St Mirren somehow still level.

The visitors have posed a threat at times, but it's another tale of profligacy so far for Rangers, who have failed to score from 13 shots.

Celtic threaten at a corner and the ball is headed around before Callum McGregor hooks in a shot that is deflected wide.

Another corner comes in and Toby Steward has to punch that one out.

The third corner is not as troubling for the hosts.

Djeidi Gassama and James Penrice combine well, but the latter can't get a shot away in the St Mirren box.

Striker Kasper Hogh is back in the Celtic line-up tonight but has not had the service so far.

This set-play is again dealt with by the Buddies before Kevin Kelsy puts a harmless header into Jacob Chapman's gloves.

Around 25 minutes in and this one is tighter than may have been expected.

St Johnstone have managed to get into some dangerous areas but their delivery has left them down.

Celtic have had plenty possession but have not fashioned too many clear chances.

Badredine Bouanani has been encouraging on his debut as another cross from the right wins Rangers a corner.

It's the debutant who will take from the opposite side. St Mirren survive but Rangers will have another corner.

Djeidi Gassama is busy again on the left, but the winger drills low into the grasp of Jacob Chapman at his near post.

That was a brilliant chance to score, eight yards. He's got to do better. I know it's bouncing.

He's really got to score.

Kelsy's decision-making is coming up a bit short, which is perhaps understandable given it is his first start at Ibrox.

He is trying to force a pass. A little bit too eager to get rid of the ball.

Rangers are offering St Mirren some glimpses of encouragement with their play at the back.

The hosts should be cruising, but this could suddenly start to feel restless for them.

Great chance for St Johnstone as Joe Cotterill connects with a low Enes Alic cross and looks certain to score but Celtic goalkeeper Sam Johnstone palms over.

Haissem Hassan lifts a cross into the St Johnstone box and Mika Baur beats the offside trap but cannot connect.

Celtic claim for a corner, believing there was a touch by goalkeeper Toby Steward but a goal kick is awarded.

Penetration, that's the bit that's missing at the moment for Celtic.

Everything's to feet, everything's passing and they're in front of St Johnstone.

Another blistering attack from Rangers, but this one ends with Djeidi Gassama blasting way off target.

Another header over the bar from Ryan Naderi after the Rangers striker is picked out by Djeidi Gassama.

Think he's penalised for a foul anyway.

Nice move from Celtic on the left and Sebastian Tounekti tries a disguised pass to Kasper Hogh but it is well defended by St Johnstone.

Chapman coming up trumps again.

At some point you have to praise his immense quality.

But Rangers have to take these chances because they are playing so well.
