Celtic are playing well against Real Madrid. Callum McGregor has hit the post but it's still 0-0.

Follow live text of that here.

Just 21 minutes in to the new Champions League campaign and Kylian Mbappe is already chasing a hat-trick, putting PSG 2-0 up against Juventus.

The France forward plays a delightful one-two with Achraf Hakimi before smashing an unstoppable finish low into the corner of the net.

Mbappe and Erling Haaland is the new rivalry to watch!

Jack Grealish cuts out a Sevilla pass and surges into the box but he's tackled. Maybe he should have passed.

A nice one-two with Joao Cancelo and Phil Foden but Cancelo's cross is cut out.

That is 11 goals in seven games for Erling Haaland at Manchester City now.

I've never seen a player that scores so many goals into empty nets. His movement and anticipation is just out of this world.

Jack Grealish cuts the ball back to Kevin de Bruyne, whose shot flies wide. Can City make their dominance count?

Manchester United left-back Alex Telles is playing for Sevilla tonight - he's on loan there - but on the left side of attack.

Good tackle from Marcos Acuna in the box to stop Phil Foden just as the City player was about to shoot. That would have been a real chance.

Erling Haaland starts a move this time, instead of finishing it off, in midfield. He finds Phil Foden, who picks out Kevin de Bruyne - but the Belgian's shot is well off target.

Sevilla are lucky to escape as they knock the ball round the box but find Phil Foden, who can't shoot.

Now Jack Grealish curls a shot into the side-netting. The £100m man cut in from the left before having that effort.

Sevilla captain Jesus Navas, who played for City for a few years, is annoyed to not get a free-kick for a foul by Sergio Gomez.

Kylian Mbappe has either scored or made an assist in his last nine Champions League appearances (seven goals, four assists).He has been involved in 54 Champions League goals in as many appearances (34 goals and 20 assists for PSG and Monaco).

It could be a long night for Juventus, they are behind at PSG after just five minutes and what a hit it is.

Neymar lofts the ball over the defence for Kylian Mbappe to smash home a volley into the far corner.

Boss Christophe Galtier enjoyed that one on the touchline.

Kevin de Bruyne crosses, Erling Haaland loses his marker and glances his header just wide of the far post.

Sevilla are feeling very confident as they casually pass the ball across their goalline and six-yard box. Modern football, eh?

Sevilla are starting to see more of the ball now. Good defending by City newbie Sergio Gomez to stop an attack.

Chelsea boss Thomas Tuchel to BT Sport: "It's an underperformance from us. We have the same story as always. We have an OK start, we don’t finish our half chances, we don't feel it when the game is already there to put to bed in the first 15/20 minutes. Then we concede one counter-attack, which is far too easy, and from there we struggled.

[Main frustration?] "Too much to analyse. I'm a part of it. We are clearly not there, where we need to be and where we can be. So it's on me, it's on us, we need to find solutions. At the moment, everything is missing."

[Thoughts on Aubameyang] "I will not talk about individuals today. We play as a team, we lose as a team."

[Players shrunk after goal] "If it seems like this… it’s hard to argue against it."
