Quote MessageWhat's really surprising is I thought Ayr would have to pick and choose their moments when to have a go, but they're just dominating. Dundee United look out of sorts, they're all over the place at the back.

Ayr United 1-0 Dundee United
Marc McNulty is on for Dundee United, with Adrian Sporle withdrawn. Can the striker called Sparky spark a revival?
Dundee 0-0 Motherwell
The home crowd at Dens goes wild as they think their team has opened the scoring but their joy is short-lived as the linesman has his flag up.
Jason Cummings was the man who had the ball in the net after good play from Luke McCowan but the ex-Hibs striker strayed just offside.

Yet again, Motherwell's Liam Kelly pulls off a good stop, as Charlie Adam fires a fine effort from distance, the keeper palming the ball to safety.

Quote MessageCharlie Mulgrew - he's a big enough boy, he's got to be stronger, it's a fair challenge from Mark Mckenzie. Tomi Adeloye actually takes too long to take his shot, he takes a touch in the six-yard box, but I think that goal is deserved.
Dundee 0-0 Motherwell
A cross into the box falls to Connor Shields, who sees his effort stopped on the line by home keeper Adam Legzdins.
The Motherwell striker could easily have a brace by now.
Tomi Adeloye
Mark McKenzie roughs up the Dundee United defence and presents Tomi Adeloye with a close-range shooting chance. The striker's first effort is saved but he is able to knock in the rebound.
We have an upset on the cards...

Ayr United 0-0 Dundee United
A big moment for Ayr United as Michael Hewitt crosses for James Maxwell, who steers the ball on target from near the penalty spot. There's not enough power on the shot though and Benjamin Siegrist is able to push the ball over the crossbar.
Dundee 0-0 Motherwell
Huge save from Liam Kelly.
Paul McMullan knocks down for Jordan McGhee but the Motherwell keeper pulls off a stunning stop to deny the former Hearts man.
Ayr United 0-0 Dundee United
Darren Watson fires a dangerous ball across the face of the Ayr United goal but none of his team-mates are quite on the same wavelength.
Here we go again.
Some goals please in these second halves, and plenty of them.

Quote MessageDundee United look a good side when they do things quickly. When they take three or four touches it allows Ayr to get back into a shape, but when it's one and two touch football Ayr can't live with them at times
