Allan Preston
BBC Scotland summariser at Tynecastle

It's been an excellent transfer window from Hearts. Craig Levein has been well-backed and turned the team around. He's got Mitchell back in and he is now playing in his more familiar role as a left winger rather than left-back.

Demetri Mitchell wins a corner, Olly Lee swings it in and new signing Jimmy Dunne heads narrowly wide. Hearts well on top early on.

On the first match of his second loan spell at Tynecastle, Demetri Mitchell is showing why the Hearts fans were so keen to have him back.

Playing wide on the left, ahead of Ben Garuccio, the Manchester United player is causing the Buddies defence problems with his slaloming runs forward.

Dundee: Hamilton; Curran, Meekings, Kusunga, Kerr; Madianga, McGowan, Spence, Nabi; Miller, Kallman

Substitutes:Parish, Moussa, Mendy, Ngwatala, Inniss, C.Miller, Boyle

Motherwell: Carson; Aldred, McHugh, Hartley; Cadden, Bigirimana, Campbell, Rose, Tait; Main, Johnson

Substitutes Gillespie, Taylor-Sinclair, Frear, Bowman, Sammon, Rodriguez Gorrin, Turnbull:

Massive chance for St Mirren to bag a rapid response. Cammy Smith plays Steven McGinn through on goal with a wonderful pass, but the skipper drags his left-foot shot wide.

Hibs' Stevie Mallan swings in a free-kick from the right-hand side and it falls to Daryl Horgan at the back post.

His volley though is blocked and the danger is cleared.

Quiet start to the match at Hope Stadium.

St Johnstone have enjoyed plenty of possession in the Hamilton half so far but without really testing the home defence.

Eamonn Brophy is pulled back by Michael Devlin. It's way outside the box, but the referee is see Devlin as the last men and the Dons are already down to 10 men.

Hearts have a penalty...

Lee Hodson and Uche Ikpeazu tangle in the box and the referee points to the spot.

Premiership leaders Hearts start strongly, Uche Ikpeazu using all of his bulk to win a free-kick immediately from the kick-off. Michael Smith rasps a volley over the bar.

It's a staggered start around the country. Who will be floored and who will be flying high after the 90 minutes?

Just a few moments away from kick-off around the country...

Only Hearts have a 100% record in the Scottish Premiership this season.

Will they make it four wins in four against St Mirren this afternoon?

St Mirren manager Alan Stubbs on BBC Radio Scotland: "There have been a lot of changes.

"Fourteen or 15 players were released in the summer. I’ve brought 11 in and sometimes it can take a little bit of time. It’s probably very similar to the situation I had when I walked into Hibernian and had to build a squad.

"I think, if you add in the fact that St Mirren find themselves in the top league, that’s where the have to adjust very quickly."

After being taken to hospital earlier this week, Hearts boss Craig Levein is "on the mend", according to his assistant Austin MacPhee, who takes the team today.

"Craig came in and saw the players this week and I think it was a really important step for him in his recovery as well," MacPhee said.

"He's set up a brilliant structure at the club as director of football and the way that everybody's worked in his absence this week has shown the quality of his work.

"Senior players we've brought to the club have been very important this week in our preparations. I'm sure Craig will be back really soon."

Steve Clarke seems content with his transfer dealing as he throws former Aberdeen forward Greg Stewart straight into the fray at Pittodrie.

However, the Killie boss was less keen to discuss his statement about Willie Collum in which he insisted he knew Gary Dicker's appeal against last weeken's red card would fail when he was informed that the referee had been handed tomorrow's derby at Celtic Park.

Motherwell manager Stephen Robinson tells BBC Scotland he is happy with Motherwell's "quiet" spell in the latter stages of the transfer window.

"It's been quiet," he said. "But we can't compete with a lot of clubs in terms of finances, so we need to do our signings in the summer. We are already looking at January because we need to get our pitch in early.

"We have done our business early and I'm very happy with what we have."

Turning to facing Dundee, Robinson says playing a side without a point brings its own dangers.

"Of course it does," he said. "I saw Dundee at St Johnstone last week and they play some super stuff. I think it's very, very early to be judging any team and I wouldn't say there is any sort of crisis at Dundee at all."

Livingston boss Gary Holt’s promised the home fans he’ll be trying to win today’s match, not simply trying to avoid defeat against a team he believes are one of the best in the league. Neil Lennon’s anticipating a physical battle this afternoon for his Hibs side and that’s one of the reasons he’s brought in Lewis Allan up front, a player he says deserves a chance and who’ll provide a physical presence up front.
