St Johnstone are coming more into the game and Murray Davidson's shot from just outside the penalty box is close to the target.

St Mirren threaten for the first time at Pittodrie. From a Hayden Coulson free-kick Danish striker Nicolai Brock-Madsen gets his head to the ball but can't direct it on target.

Ayr are piling on the pressure as a Lawrence Shankland strike is blocked by Genseric Kusunga.

Then, from a corner, Shankland, who has been a transfer target for the hosts, finds space once more for a shot and his effort is deflected just past the left-hand post.

Gary Mackay-Steven looks like he is in the mood for Aberdeen and is trying to take on St Mirren full-back Hayden Coulson at every opportunity. The winger scored a cracker in the Scottish Cup against the Saints last season.

He also sends in a corner that Michael Devlin gets to but heads wide.

St Mirren are having to withstand heavy pressure early on at Pittodrie.

Scott Wright then bursts through but shoots straight at goalkeeper Craig Samson as the Dons start on the front foot.

Queens make a good start, with Stephen Dobbie turning the Saints defence inside out before warming the hands of goalkeeper Zander Clark.

The veteran striker has been looking good again this season.

Livingston's Steven Lawless - a Motherwell youth product - cracks the crossbar with a stunning 25-yard volley within the opening minute.

We're off around the country. The quarter-finals of the Scottish League Cup awaits five more sides.

Are any going to extra-time and penalties?

For St Johnstone, Joe Shaughnessy comes into the centre of defence in place of Steven Anderson, who hasn't recovered from injury.

Aberdeen have been forced into a late change, with Niall McGinn picking up a knock in the warm up.
