It's not the most powerful header, but it's directed right into the corner.
And now the home fans are going to be right on these Benfica players' backs now.

Tom Lawrence eyes a second but his strike is gathered eventually by Anatoliy Trubin.
Ridvan Yilmaz then blasts way over.

It's quite literally their first attack - and it's a brilliant goal.
Mohamed Diomande is heavily involved down the left, he takes a magnificent touch and he shows the composure to lift his head and put the ball into a great area.
Tom Lawrence still has a bit to do, but he puts it down into the corner.
What a start for Rangers!

Incredible.

David Neres caught it well. James Tavernier was looking for a foul which didn't come. His reaction was poor.
It's a save you'd expect Jack Butland to make given his form this season.
Benfica 0-0 Rangers
First save and it's a good one from Jack Butland.
David Neres catches one well and it's arrowing into the near post, but the Rangers keeper parries to safety.

The man with the whistle tonight is Tobias Stieler.
The German was the referee for Scotland's 4-1 friendly defeat in France last year.
Looks like he enjoys dishing out a card. Handed out 12 yellows in a Champions League game between Feyenoord and Lazio in October.
Aye, twelve.
The Europa League anthem. Such a belter.
The disco lights are on as the players emerge from the tunnel.
What a place to play football.

BBC Sport Scotland at Estádio da Luz
I've seen it all now.
An eagle soaring around the Estádio da Luz, as is tradition in this arena, just minutes before kick-off.
Well trained that bird. Let's hope it doesn't deviate off script at future events.

Rangers manager Philippe Clement tells TNT Sports: "I'm not thinking about the changes, we just look game by game to see who's available.
"Ross [McCausland] wasn't ready for 90 minutes, maybe he can come in. He didn't train with the group yesterday.
"I expect a storm [from Benfica]. They have a lot of experience and quality also. It's a really nice challenge for us."
