United are pressing for a goal before half-time.

Tony Watt drifts in from the left and curls a shot to the back post. Zander Clark should be fully behind it but he spills and Nicky Clark isn't far away from poking past the keeper.

St Johnstone now have a free-kick right on the edge of the area...

Stephane Omeonga and Jack Fitzwater go into the book for multiple fouls in the space of two minutes.

There have been a few cynical fouls in the last few moments from both sides but still little in the way of goalmouth action.

How have United not scored?!

Dylan Levitt whips a corner across the face of goal. It only needs a touch but somehow it evades everyone - including the lucky St Johnstone defenders.

It's been a real derby this one. Not a lot of chances but plenty of meaty challenges.

Dundee pass up a glorious chance to go 2-0 ahead.

Zak Rudden holds the ball up and feeds Paul McMullan on the overlap, whose cross picks out Max Anderson unmarked.

But somehow he knocks the ball into the grateful arms of Ross Laidlaw.

The game bursts into a brief bit of action as Alan Forrest intercepts the ball in the middle of the park after an under-hit Funso Ojo pass and the Livi winger goes on the counter.

It comes to nothing in the end, though. Minutes later, Jonny Hayes gives the ball away to Forrest again on the edge of the box and it is agonisingly close to a second for Livi as his shot creeps over the bar.

Melker Hallberg is into the book for tangling with United striker Tony Watt around 30 yards from goal... it ends up with a St Johnstone counter.

United bring it back down the pitch and there's a few challenges in the box. The ball hits Jamie McCart's arm from close range. Referee Colin Steven sees nothing wrong.

A slight lull in the action now as Aberdeen enjoy a lot of possession but aren't doing much with it.

Young full-back Calvin Ramsay, as always, is one of their main attacking outlets, but a lack of runs in front of him is hindering his effectiveness.

Some say a bit of rain can spoil the quality of a football match but with what I've just seen at Easter Road, I beg to differ.

Hibs are trying to break on to St Mirren but every time the ball continues to fall just out of reach and four St Mirren players in a row slide in for the tackle.

Play is eventually stopped when Richard Tait, the last of the St Mirren enforcers to have a go, mis-times his challenge and goes into the referee's book.

Ross County go close to an instant equaliser.

Alex Iacovitti is inches away from getting on the end of a corner kick at the back post, but just can't connect.

It's end-to-end stuff in the capital.

Some great play between Kevin Nisbet, Christian Doidge and Chris Mueller allows the latter to have a clear sight of goal, but a wonderful challenge from Charles Dunne closes the door.

Cristian Montano cuts in from the left-hand side and runs parallel with the box before getting a shot off that was arrowing into the bottom corner.

Gary Woods, who is deputising in the Dons goal today, doesn't hold the attempt initially but gathers before Montano can run in and take it off his fingertips.

St Johnstone pressing for an opener. Callum Hendry threatening now, whipping a shot at goal that Benjamin Siegrist has to tip behind.

One goal already since he was recalled from Kilmarnock. He almost made it two, there.

St Mirren are having a go here, pressing Hibernian whenever they get the chance.

A mistake from Jake Doyle-Hayes allows Alex Greive to run at goal with only Darren McGregor to beat.

The angle is tight but the striker still gets a decent effort across goal away but Kevin Dabrowski is equal to it.

St Johnstone boss Callum Davidson was down on his haunches there as Ali Crawford’s shot hit the crossbar and bounced agonisingly on the wrong side of the line for the hosts.
