If you're a neutral, the second half so far won't live long in the memory.

If you're a Larne supporter, you're 15 minutes away from a historic first point in Europe.

If you're one of the 2000 St Gallen fans in Belfast, you're just having a good time in the stands. They are still singing away like there's no tomorrow. Vibes.

It's been a huge effort so far for the Irish Premiership side, who are the first team from Northern Ireland's league to reach this stage of a European competition. Now, can they get that first point?

A much better half from Noah so far but they are still struggling.

The chances just keep coming for Chelsea and after a scramble in the box Carney Chukwuemeka blasts one off the post.

PAOK sense the momentum is with them. They throw on Bulgaria captain Kiril Despodov with Mady Camara coming off.

Matthew Lusty and Sean Graham are introduced for Larne, with fresh legs needed as Tiernan Lynch's try to continue to frustrate St Gallen, who have lacked quality as they look to go ahead for the first time in the game.

Rasmus Hojlund getting a rare touch, Man Utd are being forced back by PAOK.

Hojlund has been a bit off the pace, he is better when he's running in-behind.

Heidenheim have looked like a completely different team in the second half.

The introduction of Mathias Honsak at the break was a masterstroke from manager Frank Schmidt.

Honsak has not given Hearts a moment to rest with his runs down the left. This time he beats Adam Forrester but his cross is cleared at the near post.

They're suddenly dropping deeper and deeper. I've seen this one before...

PAOK's corner is easily cleared although United can't do much on the break. This match has gone super stale.

Last 20 minutes. PAOK have a rare corner.

Youngster Tyrique George's full debut is over and he is going to make way for Carney Chukwuemeka.

Hearts' Alan Forrest finds a pocket of space on the edge of the area but his shot lacks power and is comfortably collected by goalkeeper Kevin Muller.

The atmosphere has gone a little flat at Tynecastle.

Do the players need to produce something to get the fans going? Or is it up to the fans to raise their voices to spur the players on?

Either way, something needs to improve here for Hearts to get back on level terms.

United are happy to let PAOK have the ball for a bit. The visitors aren't exactly eager to go on the attack.

Noah are not just sitting back here. They would really like to reward their travelling supporters with a goal.

Neil Critchley looks to his bench for the first time with Yan Dhanda and Beni Baningime going off.

Kenneth Vargas and Cameron Devlin are introduced.

Here come the changes. On are Marcus Rashford, Lisandro Martinez and Christian Eriksen.

Off go Alejandro Garnacho, Diogo Dalot and Manuel Ugarte.

PAOK also make a switch as Tiemoue Bakayoko replaces Tarik Tissoudali.

Ruud must have been disappointed that they didn't take some chances [in the first half].

But they have come out with more energy and they have moved the ball quicker.

They need a second to put the game to bed.

Should be 1-1!

Manchester United completely switch off and Tarik Tissoudali picks the ball up in the box. He's only got Andre Onana to beat but his shot is tame and the keeper easily gets to it.
