"Against 10 men, Barcelona should be be thinking about going for another goal. They're just passing it around at the moment but another goal would surely kill the tie."

As we stand, City would need to win 2-0 at Camp Nou to progress to the quarter-finals for the first time. Simple then...

Robert Thompson: City can have no complaints with that red card, Clichy has been a liability. Miles off the pace.

Ross Bentley: English teams always get red cards in big European games.

Ieuan Yusuf-George: Two very soft bookings for Clichy. Mistimed tackles but neither malicious or reckless. Lack of common sense from the ref.

Maybe Dani Alves was fit enough to continue. He certainly didn't seem to happy at being withdrawn as he smashes a drinking bottle into smithereens with his foot.

Neymar is replaced by a more defensive Pedro on the right of the attack and he takes his substitution a whole lot better.

Gael Clichy's red card means City have had a player sent off in their last three meetings with Barcelona after Martin Demichelis and Pablo Zabaleta were sent off in each leg of last season's Champions League clash with Barca.

Barcelona are back on top.

The inevitable defensive move from Manuel Pellegrini as midfielder David Silva is withdrawn and Bacary Sagna is brought on to fill in at left back for the sent off Gael Clichy. You can't help but feel the 10-man hosts would take a 2-1 defeat now.

MuLoRm: Aguero is just SPECIAL. That first touch was everything. Man City's one-man rescue package,

Helles Mammut: Nice consolation goal but to have a realistic chance to advance City need to score two or three more in this half.

Toby Foot: Barca have been sloppy fighting for second balls in past 10 minutes, City have been wanting that goal and rightfully get it.

"Just as City thought they were getting into it... A clumsy challenge from Clichy and the referee had no option. It's a shame because it looked like they were getting back into it."

Dani Alves can't continue after Gael Clichy's tackle and is replaced by Adriano on the right.

Brilliant defending from Pablo Zabaleta stops Jordi Alba from making it 3-1. The Spaniard is about to shoot with just Joe Hart to beat when Zabaleta flies through the air to toe-end the ball away

Maybe not then.

Just when City started to push, more hesitancy from Gael Clichy leaves them up against it once more. The defender is too slow and clatters Dani Alves in the knee. Clear booking - his second of the game - and he is out of there.

City are pushing now. The fans believe, the players believe and Barcelona might to be starting to doubt themselves. Less than 20 minutes remaining but this is very much game on.

"If anyone was going to score, it looked like it would be Sergio Aguero. Javier Mascherano has struggled with his pace all night. He showed great strength and pace and a great finish."

"Hope at last for Manchester City and reward for a second half performance that has at least shown some ambition. They have shown Barcelona's defence to be vulnerable under pressure - now can they do it again?"

A lifeline. Vital? It was a cracking finish from the impressive Sergio Aguero, who collects an inventive, defence-opening backheel from David Silva before smashing his shot past Marc-Andre ter Stegen.

Here comes Wilfried. City's £28m signing from Swansea is on for his Champions League debut as he replaces Edin Dzeko in attack. Time to be a hero?

IMMSY: City is going through a phase United went through when then started their Champions League journey.

Anthony Gleeson: This is just evidence that city are not as good as they thought.

Madan Roka: City much improved in the first 15 minutes of the second half. They'll be disappointed not to have pulled a goal back here.

Ivan Rakitic is presented half a chance but lifts the ball over the bar. Lionel Messi then pulls the ball out of the air with one touch, lays it back and Rakitic is crowded out.

Wilfried Bony is getting stripped to make his Champions League debut for Manchester City.

"Nasri won't be happy to be subbed off but he's not had an influence. He's not contributed enough. He's straight down the tunnel and spat his dummy out a little bit."

Midfielder Fernandinho is coming on for Samir Nasri as manager Manuel Pellegrini looks to be opting for some more steel. James Milner will take Samir Nasri's place on the right, allowing the sub to slot in alongside Fernando.
