It must be really demoralising to play at home and barely get a touch of the ball, especially for a team that is used to dominating games on home turf in their own domestic league.

Leipzig are giving their front players nothing, though.

Jack Grealish is in the wars.

He has a bloodied knee from an earlier challenge and now needs a bit of treatment after slipping in making a tackle and colliding with an opponent.

Thankfully for City, he is quickly back up on his feet.

Oh, so close to 2-0!

City pump a corner to the far post, where Rodrigo is lurking to head back across goal. Erling Haaland flings a boot out to try and steer it in, but misses as the ball flies wide.

If City play this right, they could blow Leipzig away here.

They pile forward in numbers again but fail to take advantage as Kyle Walker dwells a second too long before sending in a low ball that is cut out.

Well they have just absolutely ground down Leipzig for this goal. They've forced an error in midfield that Grealish pounces on quickly. It then goes through the legs of Gvardiol and it's a simple finish for Mahrez.

But it's all about the relentlessness of Manchester City at the start of this match.

Porto's first proper attack and Marko Grujic pokes an overly complicated effort over from outside the box.

At the other end Edin Dzeko is penalised for clattering goal guardian Diogo Costa.

The onus, of course, is on City to move the ball quickly enough and be intelligent enough in their movement to pull open a gap in this disciplined home defence.

They're getting most joy down this right side through Kyle Walker and Riyad Mahrez, but there's been no telling final ball. Yet.

It's unbelievable dominance of possession away from home. Again, you're just seeing something slightly different with how they are setting up today.

Rodri is a bit more solid in the middle, and then you've got Kyle Walker high on the right and then on the inside position. They're just rotating all over the place.

If this was a keep-ball session it would be over by now. The number of passes is incredible.

Leipzig are really struggling to make any imprint on the game in an attacking sense. They're barely touching the ball, instead using all their energy to shift from side to keep City out, taking it in turns to drive out to meet and press their man.

This really is a clash of styles. City want the ball all the time, looking to grind their opponent into submission.

Leipzig are content to give it to them, crowd them out before they can pose a real threat and then drive forward as rapidly as they can.

Abhi: I don’t understand why Man City gets blame for boring football when the opposition shows no interest in the press or to play and just park the bus

Woof. Inter Milan's Hakan Calhanoglu plays a short one-two from a corner and shoots from the left wing. His effort is tipped over by Porto keeper Diogo Costa.

The City defence does it's job again, holding a firm line to catch Andre Silva offside again.

Ederson hasn't had a thing to do yet.

I just love the position Grealish took up there. He made a really positive diagonal run into the centre. That's where you want to see Jack Grealish.

It is Mahrez who hits the free-kick, but plants it straight into the wall. What a let down.

If Inter were to win this, it would be the first time they and AC Milan won a Champions League knockout game in the same season since 2011-12.

Milan beat Tottenham last week.

Inter midfielder Nicolo Barella blazes an ambitious long-range volley ovr.

Ilkay Gundogan or Riyad Mahrez? Both fancy it...

Jack Grealish carries the ball to the edge of the home box and is pushed over. This is a very handy free-kick.

There's a giant banner that runs the length of the stand at the end City are attacking that reads 'we're on our way to Istanbul'. They're optimistic.

Wonder what happens to that if Leipzig get knocked out? It's not really something someone can just stick in their loft.
