Juventus were playing are as well as I have seen him in a long, long time, like during the 2015-16 season when they reached the Champions League final. The defeat they suffered to Real Madrid in Cardiff was a big surprise, they are back to those levels.

Not only because Cristiano Ronaldo is upfront scoring goals easily, they have great depth. Bringing Leonardo Bonucci back has been a big factor and they have been imperious.

People will look at it and say they have won it the last seven years, but Serie A was the only league last season with a title race. They do not get it all their own way and I expect them to put on a show against Manchester United.

There is a big debate in Italy whether this is the best Juve side EVER.

Over on Instagam, we've been asking fans about the best Champions League performances - head over to @bbcfootball, external to see more.

No changes for Manchester United, naming the same starting XI that played in the 2-2 draw against Chelsea at the weekend.

Man Utd XI: De Gea, Young, Smalling, Lindelof, Shaw, Matic, Pogba, Mata, Rashford, Martial, Lukaku.

We will bring the Juventus team your way shortly...

Hopefully on his walk through the traffic to the stadium, Jose Mourinho didn't buy one of these.

At what point to we legislate against such knitwear?

Like a lot of Manchester United players, Romelu Lukaku has been off the pace.

I am sick of hearing "it is going to take time". They finished second last year and we thought they would improve this year and challenge for the title.

They are hardly reaching for the stars. It looks like they are accepting mediocrity.

Marcus Rashford, Romelu Lukaku and Anthony Martial all start for Manchester United who are unchanged from Saturday's draw with Chelsea.

Kevin De Bruyne starts for Manchester City for the first time since May. The injury is done and dusted, he's back.

Sergio Aguero is on the bench for the game in Ukraine.

Team news from the late games seconds away. Eyes down people... eyes down...

The Belgian El Clasico?

Mark: Has to be Beveren vs Lokeren in the early '80s when there was a real rivalry between the two; Lubanski, Lato, Larsen, Jean Janssens, Bob Stevens, Erwin Albert, two great teams.

Manchester United have called tonight a 'match for the ages' on their programme. So that got me thinking, what for you is a match of the ages? Tweet #bbcfootball.

The half-time whistles sound in Greece and Switzerland.

AEK Athens 0-0 Bayern Munich. The German side pressed and almost broke the deadlock in added time as Arjen Robbed crosses, prompting a clearance from in the six-yard box with the goal gaping.

In Switzerland it's Young Boys 0-1 Valencia. Michy Batshuayi with the only goal, a neat finish. His side have looked comfortable and are moving level with Manchester United in second-place in the group.

There is a real sense of occasion at Old Trafford tonight. A lot of fans appear to have turned up earlier than usual and it looks as if Juventus are going to enjoy a significant away following tonight.

The German champions have reached the quarter-finals at least in each of the last seven seasons.

The run goes runners-up, winners, semi-final, semi-final, semi-final, quarter-final, semi-final.

This group then, featuring Ajax, Benfica and AEK, looks like something of an open goal.

Serge Gnabry has probably been Bayern's brightest spark down the left. He's already had three shots tonight, the latest of which sees him create space with clever feet and drill high into the side netting.

There's no escaping half-and-half scarves...even in Ukraine.

Team news from Shakhtar Donetsk v Manchester City coming up.

Something of a midfield battle in Athens but Bayern carving more from the melee as they've had seven shots so far.

You'd not think they have just one win in five as there's not a lack of confidence on show. Perhaps a lack of conviction in the box but there'll be no panic if we go another 10 minutes and end up 0-0 at half-time.

Arjen Robben slides Joshua Kimmich in behind and not for the first time, Dmytro Chygrynskiy has to come up with a key block in the area to concede a corner.

Right then, Manchester United have called tonight a 'match for the ages' on their programme.

So that got me thinking, what for you is a match of the ages?

I'll go for Merthyr Tydfil v Yeovil Town. There was a cracking rivalry there back in the day.

What's your shout? Boca v River Plate? Macclesfield v Altrincham?

I fear for Manchester United, I do not feel the togetherness. People will talk about the last two games but this is a step up - Juventus in Europe.

Juve will be ruthless, you look at the players at their disposal, Cristiano Ronaldo, Paulo Dybala, Blaise Matuidi, Miralem Pjanic - they all really good footballers.

United have to be at it from the off and need a big performance, if they win it could transform their season.

It’s a chilly autumn night at Old Trafford, but there is a decent choice of scarves on offer outside for Manchester United fans who want to keep warm and welcome back a former favourite at the same time...

That Valencia goal would take them level on points with Manchester United in second place in the group, the Red Devils play later of course.

Back in Athens, Bayern nearly lead as a ball across the face of goal just has too much on it for Robert Lewandowski to tap in. AEK are scrapping though and force an easy save from Manuel Neuer moments later. That's 30 minutes on the clock in these early games...
