Thoughts on that half?

Eamon Cassidy: No Ibrahimovic, no Verratti and no Thiago Silva, PSG are missing their spine.

Kyle Swann: I wonder why PSG are just clearing the ball and making no attack. They should try and pass it round Barcelona and score.

PSG glad to only be one down after a first-half schooling from Barcelona. The Catalans could end this tie tonight in the second half.

As well poised as it gets in Porto.

Edinson Cavani hooks a spectacular overhead kick wide, but he's a yard offside. He shouldn't be to be honest.

Watford have now gone 2-0 up against Nottingham Forest in the Championship. Matthew Connolly scored the Hornets' second. As it stands Watford are level on points with Norwich who are second, but have an inferior goal difference to the Canaries who have scored one goal more.

PSG have a ragged minute and they are lucky not to go two down. First, they over-commit at a corner and a better pass from Neymar would have sent Lionel Messi in on goal from the halfway line.

Then, David Luiz has one of his 'Playstation' moments, charging out of position to the left and being tackled by Luis Suarez. Suarez is short of support so tries to chip Salvatore Sirigu from 25 yards, but Sirigu covers his ground to save.

He lands on his shoulder and needs treatment though. More injury problems for the hosts? He'll see it through to half-time at least.

Cam Bam: A player like Carrick would make this PSG team one Of the best with his ability to pass forward and his passing range.

Live: Against a team like Barcelona, you can't just go all attack without solid defending when the ball is lost esp. with Thiaggo Silva out.

Belete Eshetea: From Bad to Worse-PSG a goal down and without their captain. Mission improbable?

The Paris crowd finally get behind their team as we tick over the 40-minute barrier. Blaise Matuidi tries to take the fight to Barca but the Spanish side are serene in defence, Javier Mascherano dictating the back-four's movements.

Love this from AS: "Iniesta's touch is the footballing equivalent of Leonard Cohen's secret chord."

Hallelujah indeed. Iniesta back to his feet after that Yohan Cabaye reducer. You don't really care for music, do you Yohan?

Yohan Cabaye with a meaty challenge in midfield, lunging in on Andres Iniesta and leaving one on him. That was naughty. Mark Clattenburg quick to whip out the card.

Stavros Makrozachopo: I really don't understand PSG's approach. Since they are behind why not have a go at Barca, instead of waiting back and defend?

Ahmed Safwan Shah: Wonder if Zlatan still thinks PSG are too good to be playing in France.

DeathApeDisco: Cavani's price tag and wages baffle me. Time and again he fluffs big moments in the Champions League.

Lovely play from Maxwell as he whips in a cross on the run to the near post, Edinson Cavani gets across Javier Mascherano but he can't generate any power on his left-footed volley. Fine play from the PSG left-back who has had some career hasn't he?

Gerard Pique goes into the book for the sort of tackle you want your defender to make, a cynical stop on halfway.

Not one member of the Barca squad is a booking away from a suspension. Squeaky clean.

Big goal towards the bottom of the Championship as Rotherham take the lead against Fulham at Craven Cottage. Matt Derbyshire's fourth-minute goal has moved the visitors above the Cottagers as it stands. Elsewhere it's Nottingham Forest 0-1 Watford and in League Two it's Burton 0-1 Carlisle.

My doubts over the clinical nature of Edinson Cavani continue. Ezequiel Lavezzi picks it up on the left, turns inside and releases Cavani into an ocean of space. A good first touch and he's in on goal, but it's a horror, bobbling off his shins and allowing Javier Maschreano to make a heroic sliding intervention.

For all the money Cavani has cost, he should be doing better. Great chance for PSG. Zlatan would have buried that.

Bayern Munich are back in the game with a key away goal as former Barca man Thiago steers in.

Neymar has brought his dancing shoes tonight. He cuts in from that station on the left and beats two men easily before dragging a low shot at the body of Salvatore Sirigu. It's almost silent at the Parc des Princes.

Madan Roka: Yes, I can definitely see Neymar winning the Ballon d'Or in the near future. but still probably after Messi retires.

Jeremiah Kariuki: The goal by Neymar may be the opening of the flood gate!

Chris Rod: Horrible defending by PSG.

Stavros Makrozachopo: I really don't understand PSG's approach. Since they are behind why not have a go at Barca, instead of waiting back and defend?

Barca have now scored 11 away goals in the Champions League this season (more than any other side), but only three players have scored them (Lionel Messi, Luis Suarez and Neymar.)

That's what they're paid for.

A huge cheer as David Luiz does come on to take his place at the back. This is a double gamble though.

1. David Luiz needs to be able to defend here. And

2. He's only 10 days into a recovery from a hamstring injury which was supposed to take a month.

A half-fit David Luiz against this Barca attack?
