Aberdeen with a free-kick. Leighton Clarkson and Jamie McGrath are over it.

McGrath hits it, he tries a knuckle-ball, and Dimitar Mitov has to palm over the bar.

Kilmarnock are showing terrific organisation and discipline when required as Rangers try to plot a path back into this one. They're struggling to get their wide men Cortes and McCausland involved so far, with manager Philippe Clement out on the touchline urging his players to stay patient and push further up the park.

Chance for Hearts to level with a free-kick near the edge of the box.

But it's straight into the wall from Stephen Kingsley.

St Johnstone are very much in the ascendancy at the moment.

They are pulling Aberdeen all over the place at the moment and clearly starting to grow in confidence and belief as this game goes on.

Marcondes just slots it home from near the penalty spot. He doesn't put his laces through it, just curls the ball into the bottom corner. It's a great finish.

Tete Yengi has been everywhere in these opening 15 minutes!

He gets a head on Joel Nouble's cross to the back post but it just skims past the outside post and into the side netting.

Martin Boyle looks like he's through one-on-one but the speedy Hibs attacker is pressured off the ball by the recovering Hearts defence.

Tete Yengi tries to get another move going for Livi.

He wins the ball in his own half and makes a lovely run deep into the Motherwell half. The ball ends up with Dan MacKay, who tries a strike from the edge of the box but it soars wide.

You have to admire the energy and organisation of this Kilmarnock team. Hassling and harrying Rangers all over the park, sharp and enterprising going forward, with Armstrong and Kennedy looking their usual threatening selves on the wings.

Can Killie keep it up for 90 minutes? They may well need to call on that strong-looking bench of theirs.

Kilmarnock's wingers, Danny Armstrong and Matty Kennedy, are so tenacious and have such quality when they win possession.

Their pressing, movement and pace are troubling Rangers down the flanks, and the latter curls a sumptuous cross in from the left, begging to be prodded home.

For Kilmarnock, alas, there are no takers.

Will Fish warms up the palms of his own goalkeeper with a firm header back to David Marshall.

A wee fright for the visiting fans there...

Rangers have responded well to going behind, with new signing Oscar Cortes particularly energetic.

The midfielder spins neatly inside on the edge of the box and bends a low shot towards the far corner.

A solid Will Dennis stop sends it behind and Connor Goldson nods over from the corner.

Massive chance for Aberdeen as St Johnstone are dispossessed in midfield. Bojan Miovski is played clean through, but he drags his shot well wide.

St Johnstone hit straight back. Matt Smith curls in a brilliant cross and Nicky Clark tries to chest it in, but Kelle Roos saves comfortably.

Both sides with brilliant chances to open the scoring.

Better from Hearts as Kenneth Vargas shows good feet before seeing his pull-back hacked clear.

Alan Forrest follows it up with a dangerous ball to the back post.

This is the kind of start Brendan Rodgers would have been craving. A goal to the good and his team are pressing Dundee constantly. They look lively and Yang's pace is causing all sorts of problems.

The home crowd are right behind the team too, which again will be to the Celtic manager's liking.
