Andreas Iniesta is stripping off. Barca need every bit of talent at their disposal to try and get out of jail here. You thought the PSG result was bad. This would be worse.

The game is back under way in Paris and PSG have gone very close. Edinson Cavani has hit the post. It remains 0-0, though.

Off the line! Rafinha gets past a couple of men in the Leganes box before producing a shot that deflects towards the goal and past the keeper before being hacked cleared by Diego Rico into Herrerin's hands.

Once again, Guerrero is clear of the Barca defence. He eyes a shooting opportunity but is denied it by the attention of Jeremy Mathieu. Was that a nudge? The ref says no.

A smart turn from Luis Suarez leaves his marker standing still and beaten, but out comes Iago Herrerin to beat the Barca forward to the ball.

Erik Moran departs and on comes Unai Lopez. It is an attacking move. Leganes coach Asier Garitano knows his team can get something out of this. Barca are vulnerable.

If an end result comes the build-up can be considered patient, but when the final ball is as woeful as Barca are producing it looks unnecessarily laboured. They take an age to work the ball to the right of the box before Rakitic side-foots a low cross straight to the Leganes keeper.

Herrerin's turn to save. Neymar is found in the box by Messi and he tries to sneak a low shot inside the away keeper's near post but out comes a leg to block and avert the danger.

Ivan Rakitic turns on the edge of the box but slices his shot horribly wide of goal.

If Leganes had a goalscorer they could be three, maybe four-one ahead. I kid you not.

Ter Stegen again to the rescue! He is Barcelona's star player so far. He produces another key save to deny Guerrero, who breaks the offside trap to go clear but fails to find the net with his angled drive. How often can the home side play with fire and not get burned?

Wayne Hollis: Saw Barca play Bilbao 2 wks ago. Defence poor then. Too much faffing about between GK & centre backs. PSG win was no surprise 

Iniesta must be a tempting option for Luis Enrique now to add some calm authority to the home side. I'm sure he would have preferred to have put this game firmly to bed without him but needs must.

The passes are ambitious but too often going astray for Barca. Lionel Messi is gliding over the turf but failing to beat men with the usual ease. This is a dysfunctional Barcelona.

Leganes really fancy this. They win another corner, which Guerrero fails to flick on at the near post before a Barca defender blocks a follow-up shot and clears.

It is half-time in Paris, where PSG are being frustrated by Toulouse. 

The first yellow of the evening goes to Luis Suarez for a high foot in on Gabriel.

We are back under way. I can't believe I'm typing this, but it is a really big half of football for Barca. Against Leganes.
