Anyway that's the end of this live page now. Thanks for joining us on a good day for Chelsea and a bad one for Manchester United.
Listen to ³ÉÈË¿ìÊÖ Radio 5 Live's Football Daily here.
See you tomorrow for Man City v RB Leipzig and Liverpool v AC Milan?
If that doesn't seal the deal I'll throw in Lionel Messi and PSG and Inter Milan v Real Madrid.
Not Anthony Taylor's finest moment tonight. The referee gave Dynamo Kyiv midfielder Denys Garmash a 'second' yellow card and then a red...
....
....
but it turns out Garmash hadn't been booked earlier so Taylor had to take the red card back.

United managed just two shots in this match, the fewest Opta have on record in any of their 138 Champions League matches since 2003-04.
Both were from Cristiano Ronaldo - and the second/last was in the 25th minute.
FT: Young Boys 2-1 Man Utd
Timed at 94 minutes and 22 seconds, Jordan Siebatcheu’s strike was the latest winning goal in a Champions League match since Lucas Moura for Spurs against Ajax in the 2018-19 semi-final (95:01).
FT: Barcelona 0-3 Bayern Munich
Barcelona defender Eric Garcia: "I think the scoreline is unfair. The first goal deflected off me, the second goal came back off the post and fell to Lewandowski. I don't think we should have lost by such a big scoreline.
"If we didn't hold the ball in midfield enough, at the end of the day, we were playing Bayern - maybe the best team in Europe. We knew it was going to be really tough."
FT: Chelsea 1-0 Zenit
This was Edouard Mendy's 10th Champions League clean sheet - in only his 13th game in the tournament.
Only Keylor Navas has ever done it quicker (11 games).

FT: Barcelona 0-3 Bayern Munich
Barcelona failed to attempt a shot on target.
That is the first time that has happened in the 186 Champions League matches they have played since Opta started monitoring that data in 2003-04.
FT: Barcelona 0-3 Bayern Munich
Since the start of last season, Barcelona have suffered three home Champions League defeats by three or more goals (0-3 vs Juventus, 1-4 vs PSG, 0-3 tonight), one more than in their first 24 Champions League campaigns combined (0-4 vs Dynamo Kyiv in 1997 and 0-3 vs Bayern Munich in 2013).

Chelsea
Chelsea scorer Romelu Lukaku, speaking to BT Sport: "I'm really happy with the win. Today was a better performance than the weekend. We have to keep growing."
On his goal: "Me and Cesar [Azpilicueta] agree on certain type of movements on the pitch. I had to get my timing right but it was a beautiful ball by him. We knew it would be tough game but we controlled it really well."
On Antonio Rudiger's run which almost led to a goal: "I expected the ball at the end! It was good. It got the team and the crowd going."
On what it would be like to win the Champions League with Chelsea: "One game at a time. Today is the first game. Now we have a difficult game at the weekend against Tottenham."

Manchester United
Manchester United boss Ole Gunnar Solskjaer: "That is football for you at the highest level. A lack of concentration, make a mistake and you get punished.
"We did that last year in Europe, we conceded two sloppy counter attacks against Basaksehir.
"Today in the last seconds Jesse [Lingard] wants to play it safe and one misplaced pass and you concede a goal. If Jesse gets that chance again he would swivel and clear it but we will learn from it."
On the decision to bring on Raphael Varane: "The signs were there in the last five minutes of the first half that they were going to get crosses into the box.
"We had to deal with their switches a lot better and I though Raphael [Varane], Victor [Lindelof] and Harry [Maguire] coped with it well. Of course a deflected goal off Luke [Shaw] for the first one, but apart from that it was the best way of controlling them. But we should have done better with the ball."
FT: Chelsea 1-0 Zenit
Chelsea
Chelsea boss Thomas Tuchel, speaking to BT Sport: "We expected a tough game because it's the highest competition in Europe and it's the Russian champions.
"We had to be at our top level. I am happy because we had to work a lot. It was not easy. It's tough to perform consistently at that level.
"Winning is good for our belief. We are not finished but we are in a good place to improve.
"The first step is done. But there are five more matches to go [in the group stage]."
FT: Chelsea 1-0 Zenit
Chelsea
More from Chelsea boss Thomas Tuchel, speaking to BT Sport: "You need the energy from the crowd and it was a fantastic atmosphere.
"It was an excellent header [from Lukaku for the goal], a well timed cross by Azpilicueta. He was brave enough to step up and we had bodies in the box.
"That's why he [Lukaku] is here. He likes to score and he's decisive for us."

Chelsea
Chelsea boss Thomas Tuchel, speaking to BT Sport: "It was not frustrating. It was tough against very strong opponents. We had to work really hard. I felt a huge intensity from us which we brought to the game.
"We struggled a bit to create chances and shots in the first half. In the second half it was a bit easier to find spaces and shoot. It was a deserved win. Hard earned. It took us a while to make them tired but I liked what I saw."

Former Arsenal and England defender on ³ÉÈË¿ìÊÖ Radio 5 Live
Chelsea have gone to a new level. The fact they have been playing under Tuchel for a short period of time they are starting to understand the way he wants the game to be played.
Their mentality is changing into a winning mentality.
To top that, they have brought in a world class striker at the top of his game.
Villarreal are unbeaten in their last 17 European matches after their 2-2 draw with Atalanta.
Chelsea beat them in the Uefa Super Cup on penalties but that's technically a draw...
