31. Zaha drives down the left and squares Maguire up and flashes a cross into the box.
United manage to scramble it clear.
The home side come again and Ziyech has it 25 yards from goal this time and blazes a shot over the bar.
29. Oh Andre!
It's a free kick on the right of centre, 20 yards from goal.
Ziyech whips it into the wall and it finds a gap between the wall and those on the edge of the wall.
But the ball goes right into the centre of the goal beyond the United keeper who gambled on the shot going over the wall.
Poor all round.
THE HOSTS ARE BACK IN IT - AND IT'S ANOTHER SHOCKER FROM ANDRE ONANA!
27. McTominay sends a decent cross in from the right which is claimed by Muslera.
He gets Galatasaray on the attack with a quick throw and they manage to all the way up the park before Fernandes trips Mertens on the edge of the box, just on the right of centre.
Fernandes is shown a yellow card and it's a good opportunity for the hosts.
25. Blimey, it should be 3-0!!
Great play from Hojlund with his back to goal initially before being sent to the byline on the left.
He smashes a cross into the box which finds Luke Shaw all alone inside the box but his touch lets him down!
United win a corner but nothing comes of it.
24. Angelino trips Hojlund just before he gets Antony clear on the right.
Again, perhaps lucky not to see a card but the United defenders will be glad of a rest for a minute or two as the hosts try to lift the pressure.
22. They've had to get a new ball as the match ball was burst - no surprise if it was from the Fernandes strike!
Boey does well to get down the right flank and flash a cross across goal. Amrabat skews his clearance and it falls kindly into Onana's arms.
20. How the hosts react to that. The whistles are a bit constant now.
Torreira wipes Antony out and a free kick is given - incredibly he's walked away without picking up a booking though.
United were 2-0 up early-ish over Copenhagen too, so they'll need to be more vigilant.
18. What a strike from the skipper - United's best goal for three days.
This place falls silent. Luke Shaw flicks a pass into Fernandes 30 yards from goal wide on the left.
He drives infield and gets around 25 yards from goal and unleashes a stunning strike into the top corner.
Muslera waves at it on its way past as it almost bursts the net!
17. Onana with a mistake in clearing it and Icardi looks to be clean through.
The keeper rushes off his line to nick it off the striker's toes.
NO PENALTY
The referee does eventually wave play on.
Was more of a handball than that disaster of a decision in Paris last night but still shouldn't have been a penalty.
On this occasion, the officials get it right.
WHAT A SAVE!!
15. It looked set to be 1-1 but for a fabulous save at point-blank range from Onana.
Maguire gets back on the line as the rebound falls to a Galatasaray player, and an eventual shot hits McTominay.
The home side are appealing for a penalty.....VAR are checking it.
14. Galatasaray get a corner from a challenge from Amrabat.
The first one defended well and it's another corner.
12. Muslera in goals ran 40 yards to square-up to Garnacho after the celebrations.
Not sure why...
11. What a start from United and Garnacho is at it again.
Yes, it's not as good a goal as Sunday but it's probably more valuable.
Antony and Fernandes work the ball well before the latter plays a tremendous one-two with Hojlund.
It comes back to the skipper who just lays it into Garnacho's path on the left and he takes a touch to settle himself before rifling it into the roof of the net.
Dream start!
THE ATMOSPHERE HAS DISAPPEARED AS UNITED'S STAR BOY DOES IT AGAIN!
GARNACHO GIVES MAN UTD THE LEAD!
8. That was a big chance for United, with a great counter attack lead by Maguire.
He feeds Antony who does well to beat two tackles and feed Fernandes on the edge of the box but his touch is rotten and he loses possession.
They were 3v2 for a moment there!
CLOSE!
5. Garnacho leads the charge for United down the left and he drives 30 yards to reach the side of the hosts' box.
He fires it in low and Hojlund shows good movement to get a yard but it's good defending to get the block in and the ball spins back off Hojlund and out for a goal kick.
4. It's Mertens' turn to have a an effort at goal.
But this strike is from a full 35 yards out and Onana saves comfortably.
3. The corner is headed over at the near post.
CHANCE!
2. Good feet from Zaha to get Icardi away into the United half and he finds Ziyech.
He squares up Luke Shaw on the cover and the Englishman gets a block in on the shot to send it spinning behind for a corner.
1' Sacha Boey already gets forward and into the box down the right hand side.
Amrabat gets back in to intercept and gets the ball away.
United win a throw-in inside their half and the jeering is already intense!
Fernandes kicks us off and we're underway in Istanbul!
But the game is upon us as Bruno Fernandes gets ready to kick us off.
United shooting from right to left as we see it.
It's a must win!
