An early change.

Marnon Busch goes off with Omar Traore brought on.

Hmmmm. That's a strange one with just 37 minutes on the clock. Busch ran off the field and didn't look to be struggling with an injury.

It's just not working for Manchester United's attack.

Bruno Fernandes finds Amad Diallo in a good position, but the winger's pass back is cut out.

PAOK will be happy.

They have been intelligent, they're keeping the ball and not giving it away easily.

It's been 15 minutes since Chelsea last scored a goal. Rubbish.

Hearts are knocking at the door.

Blair Spittal is the latest to chance his arm with a drilled shot. It looked set to nestle in the bottom corner until a leg was dangled out by a defender.

Now it's Hearts' Adam Forrester who is given a firm warning by the referee.

It has largely been a well-mannered game.

The cards won't be far away now, though, after those two incidents.

Amad Diallo is playing like he knows Ruben Amorim is watching.

The Manchester United forward is so direct. The Old Trafford fans get out of their seats every time he receives the ball.

Sarcastic cheers from the crowd every time Noah string together a few passes.

Harsh. They actually don't look too bad going forward but a few defensive mistakes have really cost them.

Tim Siersleben gets a stern talking to from Norwegian referee Kristoffer Hagenes after a very poor challenge on Hearts' Yan Dhanda.

Dhanda was looking up in the air at the ball as Siersleben charged straight into the back of him.

Fantastic ball across from Alejandro Garnacho, he whips into a corridor of uncertainty.

Amad Diallo locking up at the back post to tap it in, but he couldn't get there.

Man Utd have attacked with a real pace, but they have failed to find the final piece.

Fantastic defending from PAOK's Abdul Baba. Alejandro Garnacho zips a low pass across goal and Amad Diallo is waiting to tap in at the back post.

But ex-Chelsea defender Baba intercepts.

Hearts go route one for the first time with a long ball over the top of Lawrence Shankland.

The striker looks favourite to get to the ball for a moment until he is nudged off his stride by Tim Siersleben and goalkeeper Kevin Muller comes to collect.

Manchester United are looking open at the back when PAOK counter. This time Andrija Zivkovic holds the ball up, before smashing a shot well wide.

James Penrice makes a purposeful run into the box and his sliced shot falls to Alan Forrest who drags his effort horribly wide.

Forrest turns away to see the flag is raised for offside. Blushes spared.

Ooooh. That looked like it had crossed the line.

Marc Guiu heads it down towards goal and it's scrambled off the line before Ognjen Cancarevic gratefully collects.

Another penalty shout for Manchester United, but this one definitely won't be given.

Bruno Fernandes collects on the half-turn and feeds in Casemiro. The Brazilian goes down under pressure from a defender, but there's nothing in it. Casemiro tripped.

There's a lot to like about the way Hearts have pressed and attacked but they do look a little slack at the back.

It's far too easy for Heidenheim to get a cross in and Luca Kerber heads over the bar.

I think Man Utd look good at times.

I have been impressed by Manuel Ugarte. He has come in and done exactly what we thought he would do - he is being that fire extinguisher in the middle of the park.
