This is going from bad to worse for Dundee...

Josh Mulligan catches Joshua Nisbet in the box, and this will be game, set and match if it goes in.

Pretty much everything Nicolas Kuhn touches this season turns to gold. Or at least finds the back of the net.

His shot takes a massive deflection on its way in and that's that. Game over and yet another three points collected by the Parkhead juggernaut.

Kuhn joins Daizen Maeda on 13 goals in all competitions so far this season. Quite something to have two wide players both on that mark so early in the season.

This has been a very composed performance by Ross County - great build-up play again leading up to the second goal.

The small travelling support are now in fine voice at Dens Park. They think that long wait for an away league win is about to come to an end.

The Staggies have looked resolute at the back and with a bit of menace at the other end of the park.

A job very well done so far by Don Cowie's side.

Dimitar Mitov reacts quickly to get down low and parry clear a powerful Kyle Vassell strike from close range.

The hosts had neatly worked their way into their opponent's box, allowing the striker to fire at goal on the turn and force an impressive stop from the Dons keeper.

Marvin Kaleta races forward on the counter attack and sets up Apostolos Stamatelopoulos on the right, but the Motherwell substitute misses the target.

Dundee boss Tony Docherty is rolling the dice now in a bit to turn things round at Dens Park.

A triple change, with Curtis Main, Ethan Ingram and Seb Palmer-Houlden all coming on.

They need something to change as County are now looking comfortable and the natives are getting increasingly restless.

Ryan Leak is inches away from scoring, but somehow Ryan Astley clears off the line.

It's Ronan Hale who flicks on the corner, it could have been his goal as well.

Aberdeen substitute Ante Palaversa is booked for a reckless challenge after just 72 seconds on the park.

Centre-back Slobodan Rubezic also goes into the book moments later.

Jamie McGrath follows suit a couple of minutes after.

The Dons are losing their temper here as their unbeaten streak looks set to continue.

Ross County have brought on big Jordan White.

His physical presence will certainly give the Dundee rearguard plenty to think about if the Staggies can get the ball into him.

A very lively second half swinging from end to end so far - that said both keepers haven't really been called into any major action.

On come Kyogo, Reo Hatate and Nicolas Kuhn to replace Adam Idah, Paulo Bernarndo and Yang.

Arguably, Motherwell's difficult afternoon just got a little harder.

Fifteen minutes into this second half and United are deservedly ahead.

They've been excellent since the break and finally got some quality in for Sam Dalby to attack - and how he did.

There was only one outcome there and, right now, St Johnstone look in deep, deep trouble if United sustain this with tough fixtures to come.

Fraser Murray drags one wide after Kilmarnock caught Aberdeen short at the back.

Bobby Wales found the winger with a low cross at the back post, but he is off balance as he fires off target.

The Kilmarnock fans are having a Boxing Day party here at Rugby Park. Their team has been good value for their two-goal lead.

The Dons fans on the other hand are stony-faced behind Dimitar Mitov's goal. Even the three blokes dressed as Santa aren't looking too festive.

Everything points to United going ahead right now.

They are camped in the opposition half piling on pressure where it counts.

St Johnstone are hanging on here.

Jack Grieves is into the book for a clear, cynical shirt pull on the halfway line.

The second County card of the afternoon, after Kacper Lopata was booked in the first half.

United are motoring now.

A well-worked short corner results in Glenn Middleton slipping the ball down the side of Saints, but Kai Fotheringham's fierce shot at the near post thuds off the chest of goalkeeper Josh Rae.
