The next 20 minutes are crucial and you can tell.

Kilmarnock fans urging their side to get forward and find a third goal to put this to bed.

With Dundee's Steven Pressley making more changes, he'll feel a point is within his side's grasp.

The visitors are looking the more likely side now, with Celtic struggling to create chances to secure a second goal.

That's reflected by a nervous feel around most of this arena. The frustration is growing as St Mirren dominate the ball.

The flag goes up on the Hibs striker anyway but it looked close.

Better from the visitors, who are growing into the game.

Great chance for Motherwell to extend their lead.

Elijah Just sets up Tawanda Maswanhise, but the forward fires wide of the far post .

There's been a lot of talk about Luke Graham attracting interest from bigger clubs but he won't want to see that one again.

The Dundee defender's slack pass back to his goalkeeper is pounced upon by Greg Kiltie, who takes too long to get his shot away before the visitors recover.

That could've been the game...
