Gallacher is replaced, and rightly so.

Tiree Burchill is on in her place.

Amy Gallacher is down receiving treatment, and she needs to come off here.

She took a real nasty blow to the head a couple of minutes ago, and she's clearly not right.

It was an accidental collision, I should add.

That ball over the top that I said Celtic were looking for almost does the trick.

Kit Loferski makes an excellent arcing run, and is picked out by Caitlin Hayes.

The Celtic goal-scorer is all alone, but holds off the Valerenga defenders and gets her shot away from a tight angle.

It's straight at the keeper, but it's much better from Fran Alonso's side.

Celtic are having a decent spell of possession, which is much needed after Valerenga's recent dominance.

The hosts have looked vulnerable at the back, to go with all their attacking threat.

Valerenga want a penalty, as Olaug Tvedten is felled by Shen Menglu.

It looked a clumsy challenge, but the referee decides it's nothing more than a corner.

From there, Valerenga have two clear sights of goal from close range, but Kelsey Daugherty makes herself big and somehow keeps the scores level.

A superb double save.

Brilliant feet from Karina Saevik sees her skip away from two desperate Celtic challenges in the box, but she's slightly off balance for the shot, and it's a straightforward save for Kelsey Daugherty.

A Valerenga cross finds Ylinn Tennebo at the back post, but Celya Barclais does just enough to put the Norwegian midfielder off, and the header sails harmlessly over the bar.

Danger signs at the back for Celtic.

Shen coughs up possession in midfield, and suddenly Ylinn Tennebo has a clear sight of Kelsey Daugherty's goal.

The Celtic keeper gets down well to her right to make an important save.

Valerenga look really dangerous in forward areas - Celtic simply cannot afford to gift them opportunities like that.

That equaliser seems to have settled Celtic down.

Fran Alonso's side are popping the ball about nicely, and they seem keen to test Valerenga in behind.

A few times now, Caitlin Hayes has played a ball over the top into the channel and turned the home defence.

One to keep an eye on.

Away we go...

The players are out in front of a healthy crowd in Oslo, with a travelling pocket of Celtic fans making themselves heard.

Kelly Clark is addressing her players in the pre-match huddle - kick-off is just moments away...

I'm back, and ready to do it all again!

Can Celtic join Glasgow City in the final stage of qualifying for the Champions League?

We'll soon find out...

A job well done then for Glasgow City.

I'll be back in just under an hour's time for our second game of the day, as Celtic face Valerenga at 19:00 BST.

Go get yourself a drink, put your feet up, and I'll see you again shortly.

Glasgow City are through to the final stage of Champions League qualifying, as goals from Brenna Lovera, Kenzie Weir and Lauren Davidson secure a comfortable win over Gintra.

Leanne Ross' side weren't at their best, but it's the result that matters in games like this.

City have the ball in the corner with just 30 seconds left in Lithuania.

There will be five minutes added on.

City are all but through.

Almost an instant impact for 17-year-old Lisa Forrest. She curls a shot just wide from the edge of the box, with what must have been her first touch.
