Man Utd 0-0 Rostov
Rostov get an early free kick which is punted into the United penalty area, but Eric Bailly gets his head on it to clear.

It is not all doom and gloom, Manchester United fans.
The 1-1 aggregate score means your team are going through on away goals.
That could all change if Rostov score though. Can they? Let's see.
Rostov get us back under way.

Ricky Lee Everett: Lifeless from United - Rostov are so poor and we didn't see any genuine free flowing attacking football
Ben Virdee: Why has Mourinho changed the system to five at the back? It's so so so slow and predictable! Copying Conte? Boring like LVG!!!
Narek Verdian: There isn't really much more Jose can do, is there? The players have to deliver... how many more chances until there is a goal?
Man Utd 0-0 Rostov
Manchester United
Former Manchester United midfielder Owen Hargreaves on BT Sport: "Rostov have no threat. Eric Bailly and Marcos Rojo need to play higher, while Chris Smalling can play as a sweeper.
"United have played some good football at times and Henrikh Mkhitaryan has been at the heart of everything good."

One minute's worth of injury-time at Old Trafford did not go down well with Jose Mourinho.
He walked to the fourth official and gestured it should have been at least three.
Mourinho was still complaining as the whistle went.
United going through on away goals as it stands.

Pedestrian football from Manchester United at Old Trafford.
Just like the Louis van Gaal days.
0-0.
Man Utd 0-0 Rostov
Nearly a finger to the lips celebration from Paul Pogba, as he finds space on the edge of the box, but his carefully executed left-footed shot is brilliantly pushed away by the flying Nikita Medvedev.

Two minutes to go until half time.
"This would be a great time to score," as they say in football.
Man Utd 0-0 Rostov
Nah, not happening for him.
Paul Pogba's free-kick is high into the stand behind Nikita Medvedev's goal.

Khoren Bayramyan gets back to defend for his side, but treads on Juan Mata's boot to concede a free-kick 30-35 yards out.
Zlatan Ibrahimovic and Paul Pogba are in conversation over the ball...
Man Utd 0-0 Rostov
Before the match, I predicted five or six goals for Manchester United.
It is a good job I'm not a betting man.

Aamer Iqbal: Rostov defenders playing so well, their keeper might not even get his chance to have a blinder! 0-1 to Rostov
Man Utd 0-0 Rostov
Rostov have brought their big yellow bus to Old Trafford and plonked it in front of the goal.
How does Jose Mourinho like that?

Harrison Short: I'm a big fan of Valencia, but I'm not sure I've ever seen him use his left foot. How hasn't he been figured out?
Jay: The Rostov players are clearly not used to playing on grass.

I have never really watched a goal-line official but its all a bit odd.
They never go beyond the penalty area of their allotted side of the pitch, and never come inside the six-yard box, which means they are only covering about 15 yards in total.
When the ball is in that half of the field, they move along the line a bit like a crab, occasionally getting faster when the action gets close.
What a job.
