Harry Milne heads just over the top after some nice Hearts build-up down the left flank.

A nice open start to this game.

We're off at Fir Park and they are about to do likewise in Dundee...

In the Scottish Cup, Dougie Imrie is making his debut as Raith Rovers team boss having switched in midweek from Championship rivals Greenock Morton.

The former Morton winger's side host Alloa Athletic while his former team visit another League 1 outfit, Peterhead, under interim boss Billy Davies.

Pressure is mounting again on Dundee head coach Steven Pressley after four defeats in a row.

Indeed, the only game where they avoided defeat in their latest seven outings was that surprise home win over reigning champions Celtic.

St Mirren won the reverse fixture 1-0 in September.

But it has been equally worrying for the Buddies since and they have also only won once in seven outings - their Premier Sports Cup semi-final demolition of Motherwell.

The Premiership's top two scorers come face to face at Fir Park.

Zimbabwe forward Tawanda Maswanhise for Motherwell and Scotland striker Lawrence Shankland for Hearts have both found the net seven) times in the league.

And both players' goals have been worth five points to their sides, the joint-most of any players in the Premiership this term along with Rangers right-back James Tavernier.

Motherwell manager Jens Berthel Askou tells BBC Scotland: "It's obviously going well at the minute. Many of our players are in good shape, physically and mentally.

"Results are going our way, but we don't really have time to enjoy it. There is always the next job.

"We know this is going to be an extremely difficult game. It was a great game [at Tynecastle] - I expect in some ways a similar game.

"They are extremely hard to keep away from scoring goals, so we will probably need a few ourselves to win the game.

"Tawanda [Maswanhise] is an important part of the puzzle and has been outperforming his xG. We have a lot of different threats too, but he is in form.

"It's an opportunity for us to set the highest home ground attendance outside an Old Firm game since 2012 or something."

Hearts head coach Derek McInnes has been looking back at last weekend's loss to Aberdeen.

"Sometimes, when you lose a game, the first port of call is to look at why you lost the game," he tells BBC Scotland.

"We caused our own problems. It wasn't a game we should have lost and we were a bit annoyed.

"We have to respond. We've got to look after the ball, ask questions of them and be organised off the ball.

"Motherwell have had loads of praise and rightly so. He's improved what he's got, there was a bit of swagger against Hibs and they were worthy winners.

"There's 5,000 of our fans here today - it feels like a big game and it is."

After a run of just one defeat in their opening 14 fixtures, Derek McInnes' visitors have only won once in their latest four.

In saying that, it is maybe too soon to talk about the Hearts bubble bursting considering their 1-0 defeat away to Aberdeen last weekend was their first in 11 outings.

Motherwell have only lost once in six outings, so it should be a cracker.

Hearts came from 3-0 to draw with Well at Tynecastle in August and will be hoping to make a better start this time.

Perhaps pick of the bunch of the Scottish Cup third-round ties that do go ahead today is the Lanarkshire derby as second-tier Airdrieonians host League 1 side Hamilton Academical.

However, the biggest chances of cup shocks are perhaps involving Ross County, Montrose, Spartans and Edinburgh City visiting non-SPFL opposition.

Meanwhile, Championship sides Arbroath, Greenock Morton and Partick Thistle face potential banana skins away to lower league sides.

• Airdrieonians v Hamilton Academical
• Annan Athletic v Buckie Thistle
• Ayr United v Turriff United
• Banks O'Dee v Ross County
• Benburb v Montrose
• Bonnyrigg Rose v Spartans
• Camelon v Edinburgh City
• Dumbarton v Auchinleck Talbot
• Dunfermline Athletic v Queen of the South
• East Fife v Arbroath
• Elgin City v Stirling Albion
• Forfar Athletic v Partick Thistle
• Kelty Hearts v Brechin City
• Peterhead v Greenock Morton
• Raith Rovers v Alloa Athletic
• St Johnstone v Cove Rangers
• Stenhousemuir v Clachnacuddin
• Stranraer v Clydebank
• Tranent P-P Inverness Caledonian Thistle

St Mirren manager Stephen Robinson tells BBC Scotland: "I believe, 18-yard box to 18-yard box, we're doing all the right things. But you live and die in the 18-yard boxes. We haven't been clinical enough and we've conceded goals.

"The table doesn't lie. It might hide the fact the performances have been very good.

"We have to start turning those performances into results and, if we keep doing what we're doing, I'm confident we will.

"We need to be more clinical. We're creating a lot of chances. We've had 66 shots in the last four games and 14 of those shots were on target.

"There's no magic wand or pot of money to change it. We'll work with what we have."

One game has already been played in the Scottish Cup third round, with Championship side Queen's Park surviving an early scare to come from a goal down to beat Lowland League hosts Linlithgow Rose last night.

The game was live on the BBC Scotland channel and online - and you can watch the highlights below.

Unfortunately, one match has already been postponed today because of a waterlogged pitch - Inverness Caledonian Thistle's sold-out visit to Tranent.

Dundee head coach Steven Pressley tells BBC Scotland: "I work hard with the players day in, day out and hopefully we can produce the right type of performance. Other aspects are not in my control.

"It's easy to look at these situations in the wrong manner. We shouldn't do that. Today is an opportunity for us to galvanise our season, set us in the right way.

"We've had some disappointment along the way, but this is a great opportunity. Stephen [Robinson] has done a fantastic job with them, taken them to a cup final already, but in the league there is very little separating both teams.

"We've shown fleetingly this year we're a capable side."

Motherwell make four changes from the team that swept aside Hibs on Tuesday.

Defender Emmanuel Longelo, midfielders Lukas Fadinger and Callum Slattery, plus striker Callum Hendry, all start as Liam Gordon, Tom Sparrow, Oscar Priestman and Regan Charles-Cook drop to the bench.

St Mirren are unchanged from their narrow defeat by Celtic last weekend.

One thing to note on the bench - back-up goalkeeper Ryan Mullen is still unavailable and 17-year-old Grant Tamosevicius continues on the bench.

Full-back Scott Tanser is the only addition to the matchday squad, with Tunmise Sobowale dropping out.

Dundee head coach Steven Pressley makes two changes - and they look to be attacking ones.

While Ryan Astley slots in to replace Imari Samuels at the back, central midfielder Paul Digby has been swapped with striker Joe Westley.

Will Yan Dhanda play left wing-back again? Will Cameron Congreve drop a little further back? Perhaps Tony Yogane?

Anyone's guess. Samuels and Digby are both on the bench in any case.

Hearts welcome back centre-back Craig Halkett and captain/striker Lawrence Shankland to their starting XI after the key duo missed last weekend's defeat by Aberdeen through suspension and injury, respectively.

Derek McInnes makes two further changes to his side as defender Stephen Kingsley and midfielder Blair Spittal both start.

Michael Steinwender, Frankie Kent, Tomas Magnusson and Pierre Landry Kabore drop out.
