Goalscorer Sirlord Conteh is taken off and on comes highly-rated prospect Paul Wanner.

Wanner ed on loan from Bayern Munich in the summer and the 18-year-old has been tipped for a bright future in the game.

Let's see what he can do.

Manchester United are preparing some changes. Marcus Rashford and Lisandro Martinez look like they're about to come on.

When Manchester United led against Twente they sat back says Robbie Savage on TNT Sports.

He reckons tonight United are being far more aggressive and are hunting for a second.

Heidenheim manager Frank Schmidt had a beaming smile on his face after Sirlord Conteh nestled the ball in the net.

Schmidt is Heidenheim through and through. He was born in the town, played for the club and has been manager since 2007.

He led them to the Bundesliga for the first time in their history for the 2023-24 and delivered European football.

Schmidt is also the longest-serving manager of any German professional football club.

The referee seems sure, he had an excellent view. I have seen those given.

Huge penalty shout. Alejandro Garnacho dances into the middle and then goes down in the box right as he's about to shoot.

Was he tripped? Replays show the Argentinian caught a defender as he attempted his strike, not the other way around.

Christopher Nkunku hasn't managed to find a goal in this game so far and he'll be desperate for one.

He drives forward and lets fly from the left but his effort skims the bar and flies over.

Gustavo Sangare loops one over but there's too much on it and Filip Jorgensen collects.

Chelsea all but home dry here but they'll not want to concede.

That combination from Bruno Fernandes and Amad Diallo on this right-hand-side has been lightening at times.

Bruno releases him into a goal scoring position, the vision to see that run in-behind is second to none.

Classic counter. Bruno Fernandes flicks the ball over the top and Amad Diallo drives towards goal, but he's kept out by onrushing PAOK keeper Dominik Kotarski.

Big save to keep it at 1-0.

Manchester United hunt for a second. Alejandro Garnacho tees up Diogo Dalot, but the full-back chips his effort into row z.

Yan Dhanda tries to thread it through to Lawrence Shankland and it rolls away for a goal kick.

Hearts boss Neil Critchley likes what he is seeing and applauds the effort.

It has been some season for Critchley. Sacked by League One Blackpool after losing the opening two games of the campaign and now managing a team in Europe.

Ah. Cheap yellow for Manuel Ugarte as he breaks up an attack by dragging a PAOK player to the floor.

The free-kick is straight at Andre Onana and then PAOK's Tarik Tissoudali gets a yellow for blocking the United stopper as he tries to distribute the ball.

Joao Felix almost has hat-trick as Chelsea it around in tight spaces in the box and it comes to the Portugal forward but his low shot doesn't have enough power on it and Ognjen Cancarevic makes the save.

That was Amad Diallo's first goal in Europe since his header against AC Milan in 2021.

Marcus Rashford and Lisandro Martinez are warming up for the hosts.

Chadrac Akolo goes close with a free-kick which is pushed away by Rohan Ferguson.

That is as close as St Gallen have come in the early stages of this second half.
