I've watched Man City a lot this season, and in the final third this is the worst I have seen them play. Their passing, crossing and decision making very poor and you don't often say that about Man City
Man City 1-1 Liverpool 1-4 agg
Plenty of huff and puff from Manchester City but the quality really hasn't been there in the final third. They've had 16 shots on goal but only three on target and with 18 minutes to go, it's hard to see them scoring four goals.

Joe: We’ve equalised, City need to score four more - and yet I still feel sick. How does that work?!
Mollie: Liverpool are a totally different team when they play the attacking football that they are so, so good at. They always look uncomfortable when sitting deep, and this game is completely proving that.

Not often you see Barcelona struggling under pressure but that's the case in Italy with Roma giving it absolutely everything to get a goal that will send them through on aggregate. Radja Nainggolan tries his luck with a low strike, it's a decent effort but Marc-André ter Stegen is down to put his hands on the ball.

Dan: How might things have been if City had played the whole tie with this level of intensity?
Anon: Poor decision from pep to drop Fernandinho deep into defense. Liverpool enjoying the huge gap left in midfield now.

It's Sergio Aguero time as the striker comes on for David Silva. That's brought the crowd to life. Renewed hope.

Mo Salah's fitness was crucial to Liverpool's plans and goal number 39 of the season showed exactly why - that must surely clinch this quarter-final for Liverpool.
It is like the hope has been sucked out of Etihad Stadium after that goal. Even City's play seems to have slowed down.

Liverpool have really come alive now as Sadio Mane gets into the box from the right. He cuts the ball back into the middle of the area but there's no one in support.

Stunned silence in the home end but it's party time in the away end.
Buoyed by that goal Liverpool have suddenly come alive as Mohamed Salah plays a peach of a ball to Roberto Firmino but he takes too long to shoot and Ederson gathers.

What a finish. Guardiola can't believe it. City have just come off the pace an Liverpool capitalised. They have had to be patient, they have put as shift in and what a finish from Salah.
Daniele de Rossi (58 mins)
Skipper's penalty.
Daniele de Rossi steps up and thumps the penalty into the net.
Barcelona goalkeeper Marc Andre ter-Stegen gets a hand to it, but the strike is too powerful.
Roma back within a goal now!

Gerard Pique drags down Edin Dzeko in the box and the referee points to the spot.
Mohamed Salah (56 mins)
BIG goal for Liverpool.
Mohamed Salah has been as quiet as a mouse but he pops up when it counts to give the visitors a crucial away goal.
First decent spell of passing by Liverpool as Georginio Wijnaldum picks out Sadio Mane, he drives into the area, tumbles and the ball squirms through to Salah, who clips in coolly.
Manchester City now need four goals without reply.
