(38 mins) Kai Havertz and Dan Burn were involved in an aerial duel for a dropping ball near to the halfway line, the former ending up with a yellow card and the latter needing treatment for an elbow to the face. 

Half time: Chelsea 0 Newcastle 0

(57 mins) Despite the attentions of Trevoh Chalobah, Jacob Murphy made progress into the left hand side of the Chelsea box, prompting Chalobah to attempt a trip, clearly grab the right shoulder of the Newcastle player's shirt and then try another trip.

Referee Coote incorrectly awarded a corner and VAR official Brooks reviewed the footage before agreeing that no foul had been committed. He also decreed that there was no case for sending Coote to the pitchside monitor, despite it becoming obvious that the referee had an obstructed view of the incident.

89 mins There seemed to be little danger when Antonio Rudiger and Jorginho exchanged a series of passes in the Newcastle half just beyond the centre circle. With all 11 visiting players ahead of him, the latter stepped infield to pick out Kai Havertz as he sped into the United box from the right.

Passing Dan Burn and leaving the defender stumbling as he tried to pursue him, the German striker scored his fourth goal in three games thanks to a cushioning touch with his left foot and a flick of the same boot to take the ball beyond the stranded Dubravka, netting from six yards out. 0-1

Full time: Chelsea 1 Newcastle 0

Eddie Howe said:

"Really disappointed to lose our unbeaten run in that way, so late in the game - a moment of quality from them, a great goal from their perspective. 

"We've defended so well today: we've really minimised their chances. We've defended in a really diligent way - tactically excellent - and yeah, sucker punch at the end.

"I can't look past the penalty. I'm hugely disappointed with that decision and how they've reached that decision. Jacob's had his shirt ripped off his back. Clear penalty.

"If the referee doesn't give it on the pitch I can understand that but the VAR has to at least make the referee go and review his own decision because if he does he'll realise he got it wrong.

"It could have been a red. I'm not going to sit here and say it should have been a red. Dan (Burn) thinks it's a red. He's on the pitch. It could have been given - but the one I can't understand is the penalty.

"We lost Joe Willock and Jonjo Shelvey (on Saturday, through illness). This wasn't (the starting eleven that) we prepared, so we had to make a late adjustment.

"We didn't have any more centre midfielders, so we were forced in that way, but I don't think it harmed us. Thursday (at Everton) is a huge game."

Asked about the current situation in Saudi Arabia - where 81 convicted criminals were executed on Saturday:

"I'm just going to answer questions on the game and football. I'm still bitterly disappointed by the defeat, so it's only right that I stick to football.

"I'm here to manage the football team and coach the football team, so I'm well aware of what is going on around the world but my focus is on trying to produce a team to win football matches and get enough points to stay in the league. That's all I'll talk about....I think I've made my position clear."

Dan Burn:

"I thought it was a sending off. I can guarantee if it was the other way around, I wouldn't have been on the pitch.

"The ref said because he was looking at the ball the whole time, that's why he hadn't been (sent off). As I say, I thought it was bit naughty, but he's not given it and he's ended up scoring at the end.

"It's cost us a little bit, but you can't complain about it too much. These top quality players can punish if you switch off for a second, and that's what happens."

Isaac Hayden tweeted post-match:

"Some performance from the boys against 12 men today. Proud to be associated with the club is an understatement."

Thomas Tuchel said:

"The (Kai) Havertz goal was exceptional. Of course, we were a bit lucky today and we had a hard time on the pitch because Newcastle were physical.

"It was difficult to create chances and accelerate the game in the last 30 metres but it was important not to concede and to have the chance with maybe one quality run, pass and finish to win it and full credit because we did.

"We defended very well. The distraction level was not the biggest part today."

On his future amid uncertainty over the future of Chelsea:

"For sure, there's no doubt I stay until the end of the season. We have to wait day by day because everything can change. The situation is clear: the club is for sale and hopefully it will go through to sort things out and give us some perspective. I have no further information than you already have.

"Day by day is a good way to live your life and now we're forced to do it because there are circumstances we can't influence. In some ways that's not so nice but it gives you the freedom to focus on the things you can influence, which is our performances and show the spirit.

"The focus is on the first team - but Chelsea is much more than the first team in the Premier League. It's a massive club with huge tradition and hundreds and hundreds of people and for them it's important we show the spirit, give them a distraction and show them what we're about.

"What makes Chelsea special is the quality and commitment of the support from everybody in our building.

"My last information is we have a plane (for the Champions League away game in Lille). We can go by plane and go back by plane. If not we go by train. And if not we go by bus. And if not I'll drive a seven-seater!

"If you asked me 20 years, 30 years ago if I'd join a Champions League match at the sideline and what I'm willing to do, I'd say 'where do I have to be when?' We will be there.

"Of course organisation-wise there are some negotiations but we have brilliant guys who organise the travels and in every department there are such committed people so things in the moment feel quite normal."

"We cannot influence the situation and we are also not responsible for the situation, but at some point it's our responsibility - because we are in the spotlight and we have these games - every employee of Chelsea.

"There are a lot of people which I see on a daily basis who work for decades and are not so famous and are worried for the pretty close future if things will be alright for them.

"It's important to have the attitude right and to focus and see the responsibility, what it means to these people. And if it's just for 90 minutes…

"When we played football during Corona we could not cure the virus but we were there to give some hope, that they feel joy, excitement and this is also entertainment. This is what we do now. The matter is very serious of course."

Asked about attention focused on Chelsea's ownership compared to that of Newcastle:

"That’s a big question. Unfortunately, the situation is like this for the owners of Newcastle. What can I say? I don’t want to point the finger because comparing yourself or blaming others does not make the situation for us a different situation.

"The statement, that we condemn war and the actions from Russia towards Ukraine, there is no doubt. But we're facing the consequences actually at the moment and this is where the focus is. I hope you can understand.

"At some point we have to trust the process, the process of the league to control who owns a club. We are only employees and need to trust the process. Like you need to trust the process when you work for a company doing ethically and morally wrong things.

"Sometimes we need to ask questions of the process, how this goes; it’s maybe an ongoing process and it will never end and just reminds us to be aware and conscious about it and not look away.”

Kai Havertz said:

"Sometimes it looks like this. On the pitch, it's different. People know I'm not a player who does things like this. This guy is seven, eight foot tall and I have to jump. As anyone would know, you have to use your arms to jump.

"When I jump and he is two heads higher than me, sometimes there's stuff. I can say sorry to him because he has an injury on the head and I feel bad. But you can't tell me I did this on purpose."
