Lots of reliable players back in the XI for Chelsea, with Andreas Christensen, Jorginho, Mason Mount, Reece James and Cesar Azpilicueta in the side.

Thiago Silva, Trevoh Chalobah, Saul Niguez, Kai Havertz and Callum Hudson-Odoi make way from the 3-0 win over Aston Villa.

And there's a first Champions League start for Romelu Lukaku since his return to Chelsea.

The pressure was there, Man Utd looked like they had a good shape.

It was down the right hand side, Hefti got down the right hand side and Shaw couldn't get across to close it down.

The ball comes across and ricochets, Ngamaleu is there, it is unorthodox, he pokes at it with his left foot and somehow past De Gea.

It was coming and now we have got a real game on our hands here.

It's all Young Boys now and the Wankdorf is absolutely buzzing. So much noise.

United make a mess of clearing a corner, they're on the ropes.

Good defending by Harry Maguire to stop a good through ball and somehow win a free-kick in the process.

David de Gea is booked for taking too long with the free-kick.

The fans are moaning that David de Gea is taking too long and Cristiano Ronaldo is trying to buy a foul at the other end of the pitch. Man Utd are under pressure here.

United's last chance was in the 25th minute.

They are looking fairly comfortable despite Young Boys having 64.4% of the ball in the second half.

Luke Shaw blocks two crosses well and then Meschak Elia controls the ball out of play.

Eight of those have been from outside the box.

Young Boys have had 11 shots now, but only two have been on target.

United have as many from two shots.

What we have seen from Elia so far it looks like he has got some quality. He will be disappointed with that effort.

Five changes for Chelsea from their 3-0 win over Aston Villa.

Thiago Silva, Trevoh Chalobah, Saul Niguez, Kai Havertz and Callum Hudson-Odoi all drop out of the XI.

In come Andreas Christensen, Jorginho, Mason Mount, Reece James and Cesar Azpilicueta.

The corner is half-cleared and Meschak Elia blazes over. Another shot from range.

Young Boys win a corner as the noise levels in the Wankdorf go up.

It was the counter attack from Man Utd. It was all about Ronaldo, he was away towards the goal, the ball just didn't settle at his feet.

He was under pressure from Camara but there wasn't enough contact for a penalty for me.

That Cristiano Ronaldo incident. Mohamed Ali Camara did nudge him in the box, but not enough for a penalty.

In the other game, there's been a red card too. Sevilla's Youssef En-Nesyri is sent off for two bookings - the second for a dive. They're 1-1 with Red Bull Salzburg.

Cristiano Ronaldo wants a penalty. He breaks into the box and goes down. I'll let you know if he had a point when we see a replay.

Sandro Lauper and Jordan Siebatcheu try a one-two around the United box but the return ball is off.

I can't believe Lionel Messi isn't in the Barcelona team...
