And all of a sudden Tynecastle erupts!

A poor pass from Daizen Maeda gives Hearts a chance to break inside the Celtic penalty box.

But the ball is brought back for a free-kick as Auston Trusty tackles Pierre Landry Kabore.

Only Kilmarnock have conceded more league goals than Celtic in the period between minute 45 and minute 60 this season.

Let's see how Celtic cope...

Away we go again at Tynecastle.

A huge 45 minutes in the season, this.

I always thought Hearts would have a period in this game where they'd dominate on the ball and push Celtic back, but Celtic have handled that pressure.

Yes, Hearts had two big chances but they didn't go in.

I was surprised at Celtic's approach early on, playing the ball in behind, being aggressive. Those are things a Martin O'Neill team does, so you can see his influence.

Hearts have played the Hearts way. They've been at Celtic.

You've got to read the room though. They don't have Shankland who links the play, Kabore doesn't do that. Kabore is better facing the Celtic goal.

Play balls in the channels or over the top. Any time it's gone over the top to Kabore, he's got on the end of it and caused problems.

Those two chances Hearts have had, they have to score them.

Still no goals at Ibrox but Rangers have certainly been knocking on the door, particularly towards the end of the first half.

Dundee goalkeeper Jon McCracken has dealt with efforts from Thelo Aasgaard, Tochi Chukwuani and James Tavernier. Emmanuel Fernandez had the best chance with an overhead kick wide of the visiting goal.

At the other end, really just the one effort so far for Dundee with Callum Jones shooting at Jack Butland.

An intriguing second half awaits.

Rangers work the ball from left to right and James Tavernier curves an effort into the grasp of Jon McCracken.

The chances are starting to come for the hosts just as half-time approaches.

Almost a spectacular goal from Rangers' Emmanuel Fernandez.

He takes a high ball into the box down on his chest and overhead kicks wide.

The half-time period is when managers really earn their corn and Derek McInnes and Martin O’Neill will certainly have plenty to say to their players.

Hearts finished the better of the two sides and McInnes will be urging his players to continue as they ended the first half with the caveat being they take the chances that come their way.

O’Neil is unlikely to be too concerned given they have the advantage, but at times it's been a bit scary at the back and he will want his defence to stay strong in the second period.

Out comes the yellow card for the first time as Dundee captain Ethan Hamilton is penalised for taking out Thelo Aasgaard.

Here's another look at that altercation between Derek McInnes and the Celtic bench during Benjamin Nygren's celebration.

Would love to know what's happened there.

Big chance for Rangers.

Tochi Chukwuani is released into the inside left channel and his low shot is turned away by the left foot of Dundee goalkeeper Jon McCracken.

The hosts would probably have preferred Bojan Miovski in that situation.

Benjamin Nygren's superb free-kick splits the sides in a gripping clash at Tynecastle.

It's a pretty poor effort from Thelo Aasgaard. He could've gone either side. He could've actually run in further and committed some more defenders. Pretty comfortable save in the end from McCracken.

Thelo Aasgaard tests Jon McCracken from outside the box. It's a decent save but one the Dundee goalkeeper should definitely make.

Martin O'Neill will be happy getting to half-time at 1-0, getting them in the changing room, settling them down.

He'll be saying go back to the game plan, put it in behind Hearts, ask them questions. They don't need to invite pressure on to themselves.

More frustration for Dundee as Mikey Moore goes down in the box after being closed down by Drey Wright then Andreas Skov Olsen's cross is ricocheted back on to him and out for a goal kick.

There is certainly tension between the two dugouts, with Hearts coach Paul Sheerin and Celtic assistant Shaun Maloney now having a go at each other!
