But it is almost Madrid who snatch a third with almost the final touch of the first half. Home keeper Enaut Zubikarai goes walkabout as Toni Kroos slings a free-kick into the penalty area, but is lucky to see Sergio Ramos's header drift past the post.

PSG extend their lead over St Etienne at the Parc des Prince and it is the returning Zlatan Ibrahimovic with the goal.

You wouldn't think Sociedad have just levelled by looking at home boss Jagoba Arrasate. He looks a picture of misery on the touchline. Cheer up. A third home goal in two minutes of stoppage time will bring out a smile.

Madrid's players look gobsmacked as the reality dawns that have thrown away a 2-0 lead. And frankly I'm stunned too. But they have paid the price for switching off at the back.

Oh yes they can! Unbelievable scenes. Home midfielder David Zurutuza arrives in the Madrid box like an Intercity 125 train, powering in a bullet of a header from Alberto De la Bella's cross.

That goal has given a bit - and only a bit - of hope to the home fans. The noise levels go up a notch as Sociedad look for an unlikely equaliser. They can't - can they?

Well, well, well. Nobody saw this coming. The Basque side regain a foothold in a game where it looked they would be blown out of the water by Madrid. They still might mind.

Anyway, they halve the deficit from a well-worked corner. An inswinging corner from the right is flicked on by Xabi Prieto at the near post as team-mate Inigo Martinez ghost in at the back stick to bundle in. Shades of Steve Bould and Tony Adams there...

Somebody call the police - Real Sociedad are getting beat up badly. Madrid are looking like they will score whenever they want. They almost make it three, only Sociedad keeper Enaut Zubikarai's outstretched foot stops Toni Kroos bagging his first goal for Los Blancos.

Paris St Germain have taken the lead against St Etienne at the Parc des Prince. PSG have a forward line of Zlatan Ibrahimovic, Edinson Cavani and Lucas Moura. Pretty tasty, but the goal has come from none of them. Instead it is an own goal from away keeper Stephane Ruffier.

Play quickly switches back to the other end - and that man Sergio Ramos is again in the thick of the action. Sociedad midfielder Esteban Granero - once of Madrid and QPR fame - sees glory as a loose ball pop up invitingly about 15 yards out. But what he doesn't bank on is Ramos flinging himself into the path of his half-volley.

That wins a corner for Madrid and guess who sticks his forehead on the end of the set-piece? Yes, you're right. Sergio Ramos is there, but sees his firm header on to the roof of the Sociedad net.

Madrid left-back Marcelo is desperate for a thick slice of this goalscoring pie. The Brazilian finds more space in the home box and forces Enaut Zubikarai into a smart stop at his near post.

Stuart Mitchell:, external How anyone would buy this kit over the Madrid home kit I will never know, It's absolutely horrible.

Wale Ibrahim:, external Oh Gareth! You little genius! What a turn, what a goal.

And then James Rodriguez recycles the ball for Madrid as Marcelo steams forward to fire inches wide. The away side could have scored four or five already...

Normal service is resumed. Sociedad keeper Enaut Zubikarai has - what is known in the footballing trade - a 'mare as he jumps for a high ball with Karim Benzema. For some reason unknown to anyone but himself, Zubikarai decides to turn his back on the Madrid as he jumps and his defence come to the rescue to hack clear the loose ball.

In fact, it is all Sociedad at the moment. Iker Casillas, first choice again after being binned in favour of Diego Lopez last season, tips away a dipping cross from Sociedad's left wing. Not sure there was any danger there. But after being out of favour for so long is probably just as keen as mustard to be involved.

Sociedad are having a go though as left-back Alberto de la Bella finds himself lining up a shot on the edge of the Madrid box. Predictably he loses composure and skews his effort into the legs of Marcelo. Better though from the hosts.

How on Earth can Sociedad recover from this one? With great difficult I'd imagine. They ping a cross from the left into the Madrid box, where Sergio Ramos is back doing his day job, clearing away from home midfielder Inigo Martinez.

Now it is! Simply stunning from Gareth Bale. I'm almost drooling over my keyboard. The Welshman kippers the Sociedad defence, dragging the ball back through a defender's legs before drilling into the bottom corner.

Ooof! Sergio Ramos thumps the free-kick against the crossbar. Almost 2-0!
