Substitute Abi Harrison slides in on Emily Whelan and gifts City a free-kick in a dangerous area.

The resulting delivery is easily dealt with by Kelsey Daugherty though.

Up in Aberdeen, Thistle have a free-kick about 40 yards from goal.

Georgia Gray steps up but sends her strike well over the bar.

A Celtic free-kick turns into a Glasgow City counter-attack and Celya Barclais has to race back to prevent Nicole Kozlova from a free shot at goal.

The Celtic defender does really well to use her strength and win back possession.

A couple of changes incoming for Glasgow City.

Hayley Lauder and Sofia Maatta make way for Emily Whelan and Mairead Fulton.

Sam van Diemen slides in on Saoirse Noonan in the City box. There's a few shouts for a penalty but it looked like a very good challenge from the Dutch international.

The Thistle substitute's first act of the game sees her send a shot wide of the post from the edge of the Aberdeen box.

They're out now and back under way.

A substitution for the visitors sees Carla Boyce replace Tiree Burchill.

Back under way at Petershill, still no sign of the teams in Aberdeen.

Celtic are out very sharp at Petershill. The hosts are yet to emerge from the dressing room.

Although it's not done yet, it's going to be pretty difficult for Celtic to snatch a draw at Petershill, let alone three points. That means Glasgow City will be going top of the table at full-time.

Hibs play later on this afternoon mind you so it won't necessarily be for long.

Partick Thistle are also behind at the break, although not quite as big a mountain to climb as Celtic.

That early Hannah Stewart goal is the only thing separating the sides at the interval so plenty of time for the visitors to pull it back.

A long way back for Celtic who trail City by three goals at the break.

Lovely work in the Celtic box from Glasgow City but the resulting strike doesn't do enough to work Kelsey Daugherty in the Celtic goal.

Entering the final five minutes of the first half in Glasgow and Aberdeen - the visitors trailing in both games.

Demi Falconer saw a shot fly over the bar but that's been Thistle's only real chance in the game so far.

Only about half an hour played mind you so plenty of time to go.

Celtic look to respond immediately but Murphy Agnew loses out in the box.
