Rabbi Matondo drives in from the left and lets rip, but his shot sails wide of the post.

Philippe Clement is urging his players on. He's helpless really though. It's up to the men on the pitch to do the job.

A moment ago our TV colleagues at Sky flashed up a graphic. It showed Dundee have conceded 20 goals in the final 15 minutes of Premiership games this season.

That's the most of any team in the league.

Abdallah Sima is replaced by Ross McCausland for Rangers.

We've not seen much of Sima in the second half.

At this point in the game I could imagine a Callum McGregor out there for Celtic screaming at his players and demanding more. Rangers don't have that. Maybe they are missing Ryan Jack?

Rangers are wide open as Dundee steam forward.

Owen Dodgson crosses to the back post, where Jordan McGhee controls.

He picks out Lyall Cameron, who takes a touch and strikes the ball, but his effort is blocked.

Incredible.

Up the other end, Dara Costelloe's cross is turned behind by James Tavernier.

Dundee corner.

But it's too high from Owen Dodgson.

Cyriel Dessers is fed the ball on the break and drives for the edge of the box.

He cuts on to his weaker left foot and smashes a shot on goal, but goalkeeper Jon McCracken leaps in the air to push it over.

Dara Costelloe has misplaced two easy passes since coming on for Dundee. Both with Dundee in good attacking positions.

He'll need to sharpen up or his manager might recall him to the bench.

Rangers have dialled it up again and are playing with a little bit more aggression.

The intensity has dropped from the first half.

Rangers seemed to have the bit between their teeth, but they've fallen off a bit again.

Dundee have gone further and further back the pitch. Tony Docherty maybe sees Curtis Main as a guy who can hold the ball in and get Dundee up the pitch.

Amadou Bakayoko is replaced by Curtis Main for Dundee, and the big striker took his time getting off the park as he applauded the fans.

Not sure what the point of that is, it'll be added on at the end.

Dara Costelloe is also on for Scott Tiffoney too.

Tom Lawrence is trying to make things happen for Rangers.

After a corner he manages to squeeze a shot on target, but Jon McCracken makes the save.

Silva was walking off in a sulk as he did on Sunday as well. Having Matondo on the pitch will provide much better balance.

Rangers make a triple change.

Todd Cantwell, Fabio Silva and Kemar Roofe go off.

On come Cyriel Dessers, Rabbi Matondo, and Kieran Dowell.

As you can see below, Roofe managed just one touch in the Dundee box in his 56 minutes on the pitch.

It was a header that drifted well wide.

Rangers are pinning Dundee back, but then a wonderful pass from deep from Luke McCowan finds Amadou Bakayoko.

Rangers manage to recover, but what a ball from McCowan. He has to be among the nominees for player of the season.

If Silva had read the situation just a fraction earlier, it would have been a tap-in.

Good stuff from Tom Lawrence as he squeezes in between two Dundee defenders and hooks the ball across goal.

Jordan McGhee is well positioned to sweep behind for the corner.

Dundee launch a free kick into the Rangers box, but it's defended by the visitors.

Jordan McGhee goes down in hope more than expectation as he tries to receive a pass through, but no free kick.

No changes, by the way.

Dundee's injury-enforced switch of Antonio Portales for Joe Shaughnessy at the back is the only substitution so far.
