Atletico Madrid are sitting back in typical fashion and it's Manchester City with most of the possession. Atletico, however, have been looking for space in behind Nathan Ake on the left side of City's defence.

City getting into their stride inside the first 10 minutes.

It's the roaming full-back Joao Cancelo cracking a shot from the edge of the box which is blocked in the six yard box.

Atletico have gone into a nice rigid five in a very straight line. There is a lot of respect out there.

There's a roar from the home fans as Rafa Silva surges forward. He tries to muscle his way past Ibrahima Konate which would put him clear on goal but Konate wins that battle.

Naby Keita then sends a looping header over the bar from a decent Andy Robertson cross.

Patient possessional dominance for Liverpool in these early stages as they look to settle this boisterous home crowd.

No chances yet, the ball hasn't been anywhere near either goal so far with the visitors passing around in midfield.

It's a 100m sprint between Nathan Ake and Marcos Llorente down the left as Joao Felix sends a ball in behind the high City backline.

The Dutchman, though, has enough pace to keep his nose ahead of the Spaniard, winning the ball with a perfectly timed sliding challenge.

Jack: I never get why City fans boo UCL anthem. If you don't like the competition don't attend the games in it.

There are 63,000 fans in attendance for this sell-out fixture, 3,000 of those are Liverpool fans.

The home fans are making an incredible noise right now but who will be cheering loudest come full-time?

This is a hard game to call but City should win it if they are on their game.

Under way in Manchester and shortly after in Lisbon.

You can see who's doing which game now so direct feedback accordingly.

I really don't believe that any of the managers are thinking we'll rest people. They need to win. It becomes a habit. It just breeds confidence it is muscles memory. I don't believe it is time to rest anyone.

The Benfica eagle is flying across the stadium which can mean only one thing - kick off is moments away.

It is a difficult one but the draw could have been worse. All the talk has been about the gamesmanship and how the teams will line up.

I think teams have had more joy against Manchester City when they have put a back three in because the space is not there for City especially if they play a little bit slower.

Dion is all set.

While struggling for most of the domestic season, Benfica's best moments have come in the Champions League: beating PSV Eindhoven in the play-offs, Barcelona in the group stage and Ajax in the last 16.

It's much more than they could have hoped for, but they want to keep their European adventure going.

If they do so, they will have emulated side that caused a major upset by knocking Liverpool out of the Champions League last 16 in 2006.

"I'd say Liverpool are even stronger now, but back then they were the title holders and also a very difficult side to play against," former Benfica centre-back Ricardo Rocha, who played for that 2006 team, told BBC Sport.

"It didn't stop us from believing we could still go ahead and so we went on to beat them in both matches. This is the mentality for games like these."

Liverpool boss Jurgen Klopp, speaking to BT Sport about his team selection: "It is quarter final of the Champions League and we have to prepare for it with all we have.

"This is a big chance for Benfica as well, a big challenge yes but a big chance as well so I am not surprised they will give it a proper try.

"We have not thought for one second what result I want tonight. We just focus on the game, we respect them a lot."
