Celtic are rampant.

Adam Idah bursts into the box and smashes towards the near post, but Kieran O'Hara gets a strong hand to it.

The phrase 'bang at it' seems to cover this Celtic performance so far. With a title on the line, you'd probably expect that.

Great intensity, energy and a clinical edge. Three big chances, three goals. That is surely that.

Barring the best Kilmarnock comeback in recent memory, Celtic are the champions.

They've saved their best form for the key part of the season. If they win here, that will be 22 of their last 24 points hoovered up.

Dan Phillips has to do better there. Nicky Clark lays of to the Trinidad and Tobago international and, from 10 yards, he blazes high over the bar.

St Johnstone are creating chances but they don't look like taking them.

Steven McLean is now elevated from fourth official to run the line in place of the stricken assistant ref.

That, alas, is the pick of the action so far.

Duk does well to put himself into an area to shoot but his deflected attempt thumps off of the post with Graeme Shinnie's follow-up not troubling the keeper.

The hosts are dominating so far.

Liam Donnelly gets lucky.

If he catches Reo Hatate any higher, he's off. His lunge on the Celtic midfielder warrants a yellow.

Stevie May - that is a sitter.

The defending from Will Nightingale is poor, May steals in behind him and goes one-on-one. The St Johnstone forward has almost the entire goal to aim for and puts it straight at the keeper.

Scott Tanser and Jaden Brown threaten now. St Mirren are really on it tonight, Hearts are not so far.

We have a stoppage due to an injury to assistant referee Drew Kirkland, with the fourth official Steven MacLean possibly going to run the line for the rest of the match.

Already a four minute delay...

Liam Scales lines one up from around 25 yards out. The centre-back leathers it but Kilmarnock keeper Kieran O'Hara tips over.

How on earth are Aberdeen not ahead? The ball fell to Dante Polvara on a plate, seven yards out - and he put it wide.

Putting it wide looked a harder thing to do than scoring.

Huge opportunity for Ross County. Simon Murray clips a beautiful cross to the back post where George Harmon flies at the ball, but Dimitar Mitov makes a fine save.

Aberdeen should be ahead.

Junior Hoilett drives into the box and forces Shamal George into a low save, the rebound falls to Dante Polvara inside the six-yard box with the Livingston goalkeeper still on the deck.

He has to score but he somehow sidefoots it wide of the post.

First real chance and it comes to Ross County. A simple long ball that Ryan McGowan can only flick backwards. Jordan White runs onto it and fires it low, but Dimitar Mitov gets down well to save.

St Johnstone respond well though, with Adama Sidibeh flashing his header just wide.

This could be anything for Celtic tonight.

James Forrest bends one with his left foot from the edge of the box, but it curls just wide.

A tale of two killer passes - Matt O'Riley to Adam Idah and Reo Hatate to Alistair Johnston. Incisive, ruthless and 2-0 Celtic.

My cup of tea was still hot and Celtic had already ensured that tonight's the night the title will be won. Unless Killie can find three, which they won't.

How many Celtic can find is the question. They look incredibly sharp.

Aidan Denholm drives into the St Mirren box and gets a shot on target, but it's a tame effort which Zach Hemming saves.

Up the other end, Mikael Mandron is slipped through and fires just over.
