James Tavernier dinks it in and Leon Balogun helps it into the centre of the box, where Todd Cantwell puts it wide.

That's a chance on second viewing.

Just as I say that, Cyriel Dessers wins a foul as James Bolton slides through the back of him,

Too far out for a shot, maybe...

Rangers might want to think about upping the intensity here.

This is quite a big deal if they haven't realised.

Todd Cantwell is offering nothing and neither is Dujon Sterling.

Dundee: McCracken, McGhee, Portales, Lamie, Dodgson, Mulligan, Sylla, Boateng, McCowan, Tiffoney, Bakayoko.

Substitutes: Sharp, Astley, Main, Robinson, Robertson, Howley, Donnelly, Mellon, Costelloe.

Celtic: Hart, Johnston, Carter-Vickers, Scales, Taylor, O'Riley, McGregor, Hatate, Kuhn, Kyogo, Forrest.

Substitutes: Bain, Palma, Idah, Yang, Nawrocki, Iwata, Bernardo, Kelly, Ralston.

Rangers have about half an hour to potentially save their league season.

A draw here would give Celtic the chance to go five clear with four games to play.

It's been really poor from Rangers in the second half.

There is no cohesion in the team and nobody is taking is a grip of the game in a Rangers shirt.

Rangers are not playing like a side with a title on the line.

Right up the other end, Ross McCausland comes through the back of Ryan Strain and it's a foul.

Leon Balogun heads away the delivery.

An excellent pass from John Souttar breaks the lines and finds Cyriel Dessers, who takes a shot that's never on.

Poor decision making.

Fabio Silva's afternoon is over by the 55th minute.

Another unconvincing display from the Wolves loanee, who is replaced by Ross McCausland.

St Mirren smother Dujon Sterling and win the ball and a foul.

The free-kick is pumped into the box but Rangers clear it.

There's a breakdown in communication from the Rangers players here.

They are a wee bit disjointed.

A few points of the finger at one another. They need to get together again.

John Lundstram looks to pick out Fabio Silva with a pinpoint cross-field pass.

But the Rangers man is penalised for a nudge on the back of his marker.

Another bright start from St Mirren.

You would expect Rangers to grow into the half as they did in the first.

But Robinson will be pleased with the first few minutes here.

Moments later Rangers break forward again.

But again it's all too scruffy in the end and a three-on-three attack is spurned.

Mohamed Diomande tries an ambitious one up the other end but it's blocked by the St Mirren backline.

I wonder how long Philippe Clement will wait before making a change or two.

He wasn't happy at all as he headed up the tunnel at the interval and there's no great upturn in Rangers' intensity at the start of the second half, with some mistakes creeping in already.

Conor McMenamin now attempts to get to the bye-line but he's ushered out by John Lundstram.

Almost instantly a pass through the heart of Rangers comes close to reaching Conor McMenamin.

A touch off John Souttar helps it reach Jack Butland though.
