Not sure it is a chance, per se, but Rayo have a sighter. Barca dilly, dally and fail to sufficiently clear a cross into the box. Andres Martin sees the headlines on Marca tomorrow morning and goes for glory... high and maybe wide.

Anywhere will do for Rayo as they bid to reach first base. Ivan Martos boots into touch as the Segunda Division clear their lines.

Is there one last chance for either side before the oranges?

Looks like the Catalan giants have an additional two minutes to stick their noses in front before the break.

Lots of huff from Barcelona but no puff.

And the team in front of the television might be needed again...

Trincao - who has been Barca's brightest spark - bursts into the box from the right, tangling with Fran Garcia and going down.

Pink shirts surround the ref, who shakes his head. A coming together, I think.

Reminder we have VAR in the house tonight (well, in the Spanish version of Stockley Park) and they had a look at that block earlier from Ivan Martos. No case to answer.

Looking ominous now for Rayo. Can they see it out until the break?

Barca straight back on the attack when the games restarts, a shot from De Jong deflected inches wide.

That's three lives lost. Not sure how many they've got left.

Stoppage in play as someone in the technical area - a member of the Rayo backroom staff, I think - tells the ref something he doesn't like hearing. Red card.

Should be the opener!

A swift counter after that Rayo attack sees Barca winger Trincao skip away on the right... he's through. But he shots straight at Rayo keeper Stole Dimitrievski who beats the ball away - only as far as Riqui Puig.

The midfielder calmly takes a touch and goes for the corner... the ball hitting Rayo defender Ivan Martos and whacking the left-hand post.

Pinball. And Rayo win the jackpot.

Tidy football from Rayo! A neat move ends in Yacine Qasmi slipping the ball towards Oscar Trejo, but Neto is alert to race off his line and gather.

Rayo manager Andoni Iraola is forging a good reputation in the dugout. The 38-year-old, decked out in a smart wool overcoat, looks happy with his side's performance so far.

Well, I say a third of the way through... if the score is level after 90 minutes then it will go to extra-time. All to be done and dusted tonight.

Third of the way through and pretty even steven. Barca have come the closest through Frenkie de Jong's sliding effort against the Rayo bar.

Ronald Koeman does not look happy. The Barca boss grimaces after barking some orders out from the touchline.

This diagonal ball into the Barca box is proving to be useful for Rayo. Similar to the one a few moments earlier, another is arrowed in from the left. Catena peels off to the far post to meet the ball and direct it into the six-yard box, but some pushing and shoving from the home side is penalised.

Steady flow to this game. Rayo win a free-kick on the left and a floated ball is met by the head of Mario Hernandez. But there is not enough power to trouble Neto in the Barca goal.

And suddenly Barca are on the attack. Antoine Griezmann looks to be in on the left, but his touch is tad heavy and runs through to the Rayo keeper.

The home side manage to build up some possession and territory, almost profiting from some casual defending by Junior Firpo.

The Barca left-back flicks a leg at a Rayo cross from the left, Oscar Trejo scurrying in on the hunt for the loose ball. That sharpens Junior's focus and he clears the danger.

Pretty even so far. Barca enjoying more possession, but Rayo not being overwhelmed.

Big let off for Rayo that one. Is this another chance? Lionel Messi shapes to shoot, but his long-range effort is gathered comfortably by Stole Dimitrievski.

Barca revving up the engine.
