Real are playing some nice football. Lucas Vazquez sprays it out to Ferland Mendy on the left but his pass towards Vinicius Jr in the box is poor and cut out.

Good defending by Ozan Kabak to stop the threat of Vinicius Jr as the Real Madrid speedster broke into the box and tries to cut inside.

Plenty of Manchester City possession but no shots on target yet with just over a quarter of an hour gone.

Dortmund are looking uncomfortable at the back trying to play out because City's press is so high. When the keeper gets it, the whole of the back four squeeze up, which pushes the midfield players up.

Trent Alexander-Arnold drifts inside but his through ball to Diogo Jota is cut out by Eder Militao.

Now a TAA cross is headed away by Lucas Vazquez.

Better spell from Liverpool.

Pep Guardiola is very animated on the sidelines as Manchester City patiently try to build. Dortmund, as Phil mentions below, started well and City look to be trying to lower the tempo a bit.

Good, open start to this Champions League quarter-final first leg and certainly no question of Borussia Dortmund coming here with a negative mindset despite recent indifferent form.

Lots of vocal encouragement, as usual, from City's support staff and substitutes for the players out there battling for a place in the last four.

Basically Liverpool's first attack but Trent Alexander-Arnold's cross is deflected into the arms of Thibaut Courtois.

Vinicius Jr goes close for Real Madrid now. Ferland Mendy gets beyond Trent Alexander-Arnold too easily and crosses for Vinicius, who heads wide.

Real Madrid appeal for a penalty but don't get it. Vinicius Jr runs down the left and crosses for Luka Modric, who is knocked over by Georginio Wijnaldum on the edge of the box.

VAR takes a look and it turns out it was outside the box AND not a foul anyway.

Really tidy football from Dortmund. Keeping the ball, moving it really well.

When you're young like Haaland and Jude Bellingham, you're fearless. You will try things, you want to stamp your authority and personality on the game. It's good to have a mix of seniors and youngsters in the side.

Mohamed Salah looks to take advantage of Real Madrid's makeshift defence as he skips past a challenge in the centre circle but Ferland Mendy is across to stop him.

Left-back Mendy is the only one of Real's first-choice back four available today.

A chance for Jude Bellingham as he receives the ball inside the box but his shot from close range isn't a good one and Ederson makes the block. The ball is loose but dealt with before Erling Haaland can pounce.

Good defending from Mahmoud Dahoud as he steps in to get the ball off Ilkay Gundogan as Manchester City threatened to open up the visitors.

This is Liverpool midfielder Fabinho's 50th Champions League appearance.

He actually played for Real Madrid once, in a 6-2 La Liga win over Malaga in May 2013.

An early bit of action for Ederson as he punches the ball away from the head of 19-year-old Ansgar Knauff, another youngster in this Dortmund side.

Liverpool half-clear the corner and eventually Casemiro is flagged offside. Five minutes in, the Reds yet to get going.

Karim Benzema plays a through ball to Marco Asensio and his shot from a tight angle is blocked by Ozan Kabak. Corner.

Steady start so far on a chilly night in Manchester with the home side dominating possession. It will be interesting to see how Jude Bellingham gets on. His former side Birmingham are also in action tonight, a couple of hundred miles south of Manchester.
