It eventually falls to substitute Wiesner, who takes a poor touch and can't connect with the ball properly at the back post.

Only a couple minutes into this half but already Sparta look far better on the ball and they win a free-kick wide on the left.

Half-time changes for Sparta.

Wiesner and Laci are on for Gomez, who had a bit of a 'mare, and Olatunji.

Jonathan Sutherland
BBC Sport Scotland at Ibrox

You may recall when these sides last met at Ibrox two years ago in the Europa League, Sparta defender Filip Panak had a nightmare moment when he lobbed the ball inexplicably across his own goal, allowing Alfedo Morelos - remember him? - to bullet home as Rangers won 2-0.

A very similar story tonight, only this time James Gomez is filling in for Panak in terms of giving the home side a huge helping hand with an error strewn defensive display.

But that should not take away from what has been a highly impressive half from Rangers. The players look energised, keen to press the play high and get the ball forward quickly.

Under Philippe Clement they look clear in purpose and intent.

Despite having the smaller percentage of possession, Rangers have pinned Sparta Prague back in their own defensive third with relative ease throughout the first 45.

Just shows that possession ain't everything, it's how you use it.

Aberdeen got battered, but they stood up to it. They had to show they were brave and courageous.

They had good organisation but on the negative side, some of the set pieces they did not defend particularly well. They rode their luck but scored two fantastic goals.

The travelling support can be well pleased, the players can be more than happy and Barry Robson can rightly say that he's proud of what his players gave him.

Aberdeen manager Barry Robson: "I was so proud of them tonight. They gave us everything.

"This is a team who beat Eintracht Frankfurt here. This is a team who beat Olympiacos 4-2 at the weekend. This is a team who have been heavily invested in. We came and we went toe-to-toe with them.

"They are a new team. They haven't spent a lot of time on the training pitch together. They're also in a cup final, so we can only grow.

"We lacked that bit at the end, but you've got to remember this is real top quality we're up against."

Let's get some Aberdeen reaction...

Rangers have had an excellent opening 45 minutes.

Sparta Prague have been really untidy and have given away goals.

That being said, Rangers have been on the front foot and have been aggressive and created chances.

In you're Rangers, first halves don't get much better than that.

Two fine finishes from Danilo and Todd Cantwell have the Ibrox side cruising to a Europa League win.

Arguably the best 45-minute display of their season so far.

Abdallah Sima looks to breeze past Martin Vitik, who takes no chances and just chops him down.

Yellow card.

Rangers' pressing has been top notch.

This is a revitalised team we're watching.

Todd Cantwell sends poor James Gomez to the Ibrox kiosk and he's through.

But his finish, from a similar angle as his goal, is saved by the foot of Peter Vindahl.

Borja Iglesias is the man who as notched the opener for Betis against Aris Limassol.

That's not too far away.

James Tavernier bends one from about 25 yards, it's curling and it's curling wide.

Tavernier has just tried a Cantona chip.

That just shows you the confidence Rangers are playing with.

This is the best I've seen Clement's team play.

They are fluid and they are getting the ball forward. When they lose the ball, they are all getting back and working hard. It'll just be interesting to see if they can sustain this pressure.

Sparta Prague have been all over the place - which has been caused by Rangers' press.

James Tavernier goes for a cheeky one, dinking the ball towards the back post.

The keeper is wise to it though.

Rangers have looked a different side - enthusiasm, ability, determination.

Guys like Sima, Cantwell, Barisic have had a bit of a lift.

But it is still very early.
