Huge chance for Rangers and Youssef Chermiti.

Stephen Welsh's header is blocked by the Rangers striker and he's one-on-one, but he pokes his effort straight at the keeper and lashes the rebound off a covering defender.

That should really be 2-0.

A goalless first half in the driving rain at Falkirk.

That's not to say it's been a dull affair, with both teams playing neat, progressive football despite the conditions.

Dundee will be happier with their performance. They've looked dangerous in possession, with Luke Graham in particular driving the play forward. They haven't created many clear-cut chances, with Graham and Simon Murray seeing efforts blocked, and Cameron Congreve firing wide.

Despite Dundee's positive play, Falkirk had the best chance of the match, Dylan Tait's close-range prod blocked and cleared.

Marcelo Saracchi's strike is the difference at the break.

Celtic will be in slight disbelief that it's only one.

How close was that?!

Stephen O'Donnell sclaffs a back-post shot into the ground, but it loops up over Jack Butland and heads towards the back post.

Motherwell players are waiting but Rangers midfielder Nico Raskin somehow flicks the ball off the line with his head.

A remarkable clearance under pressure.

Motherwell threaten again.

Tawanda Maswanhise latches on to a ball over the top and beats Jack Butland to it. The angle is narrow, but Maswanhise manages to square it up and smacks the post.

Did Butland get a touch on that? The referee says no. Goal kick only.

It's gone a bit quiet at Parkhead since that early flurry of chances.

Best chance of the half, and it comes for the home side.

The ball is fired across from the right and, after a couple of ricochets, Dylan Tait can't force his effort past Jon McCracken from six yards out.

They may be playing into a very strong wind but it’s been Dundee who have been the more creative side in the opening 30 minutes.

What's really impressive from Motherwell is that they're so sharp.

It's the one touch football, the movement, the running off the ball. And they're causing Rangers problems.

Motherwell are dominating the ball. Rangers have to respect the quality they've got.

Dundee have played their way into this contest and are constructing some neat passing moves through the heart of the Falkirk defence.

One of them results in Simon Murray seeing a close-range shot blocked, before a trademark driving run and one-two from Luke Graham ends with the defender earning his team a corner.

Certainly no sign of fatigue from their weekend exertions at Parkhead.

Rangers manage to get up the pitch for the first time since their goal, but Tochi Chukwuani's driven effort glides by Calum Ward's right-hand post.

The visitors look dangerous on the break.

Some nice football from Motherwell. Callum Slattery is showing some really nice touches, while Elijah Just has nicked the ball off the toes of a few Rangers defenders.

However, the hosts fail to make the most of two free-kicks from dangerous, central positions. Those are the kind of chances Askou was talking about pre-game.

There's a lot of gegenpressing going on at Fir Park.

That's the German term for closing down opponents at a furious rate.

No one has a second to dwell on the ball.

Arne Engels has gone down for Celtic with what looks like a quad problem.

Reo Hatate is on in his place.

It's been an electric start. Motherwell could have taken the lead but it's Rangers on the break.

What a lovely weight of pass. The timing of the run, Raskin did not panic, he just picked his spot down to the keeper's left-hand side.

That's the first goal Motherwell have conceded at Fir Park in nine games.

The last time they let one in at home, Danny Rohl had not yet taken over at Rangers.

Celtic pour forward again before Sebastian Tounekti fires well over the bar.

This could be anything.

Decent start in Falkirk, with both teams fashioning early shooting opportunities.
