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.

Manchester United drive forward again but Alejandro Garnacho overhits a pass and the attack ends.

If anyone wants my opinion on the penalty, I think it's one of those referee's call.

If it's given, you're probably not overturning it.

PAOK defender Abdul Baba didn't win the ball, but then again he never exactly tripped Diallo over, more shoulder-barged him to the ground.

Noah head coach Rui Mota is pacing the touchline and shaking his head and rightly so.

It's been way too easy for the home side so far.

The TNT commentary team have just mentioned that Hearts goalkeeper Craig Gordon made his European debut for Hearts 21 years ago yesterday.

Remarkable.

Gordon, who enjoyed spells at Sunderland and Celtic after leaving boyhood club Hearts, is now 41 and still going strong at Tynecastle.

Amad just earned himself a huge ovation for chasing down a PAOK defender to force a throw deep inside the visitors half.

It is not just managers who appreciate a concentrated high press, fans do too because it is visual and they can see the effort it requires.

David Beckham used to do it a lot when he played on the right side of midfield for Manchester United.

Anyone can work hard.

Amad Diallo again, an excellent cross in, he shifts the ball and delivers an exquisite ball in.

That's why you deliver it first time into the box as you have Rasmus Hojlund attacking it.

Frankie Kent muscles his way in front of his marker at the far post but his diving header is into the side netting.

Hearts are creating so many chances.

The closest Manchester United have come. Amad Diallo whips in a deep cross and Rasmus Hojlund leaps above his marker but heads one straight at the keeper.

Hearts 0-0 Heidenheim

A cute lay-off from Lawrence Shankland finds Alan Forrest but his shot is straight into the face of Luca Kerber.

His arms were tucked behind his back and his nose has taken the full brunt of that effort.

Kerber is helped off the field by the Heidenheim medical staff as he gets a bit of tissue stuffed up his nose. He's going to need a new shirt too by the looks of things.

Play restarts with the Bundesliga club down to 10-men.

VAR disagrees. Just a coming together.

Diallo was travelling at speed. He's looked very dangerous so far.

I think that's a penalty. There is real contact on Amad Diallo. He dribbles into the box and any contact on him is a penalty.

Amad Diallo goes down in the box under a heavy challenge from Abdul Baba.

The referee says no, but VAR are checking it.

As expected, St Gallen have dominated the ball since falling behind as they look to fashion an opportunity to equalise.

Mihailo Stevanovic fires one goalward after a corner drops to him on the edge of the box, but his strike is straight at Rohan Ferguson, before Chadrac Akolo blazed over from inside the box after another corner.

Larne know they will have to defend well to preserve their lead.

Noisy or not, it's the home team in total control at the moment.

Manchester United have a few corners, but they're all headed away.
