Until next time...

Barca tried everything but Rayo Vallecano take a share of the spoils.

Radamel Falcao has the ball in the net but he is offside. That's the third time a goal has been ruled out for offside this evening.

The wait goes on.

Sergio Busquets is sent off for a second yellow card. It comes after an elbow to the face of Radamel Falcao.

He has no intention of playing the ball there and he has to walk.

EIGHT MINUTES TO BE ADDED ON.

How will it finish here?

The ball is in the net... But it's offside for the second time in the game.

Debutant Franck Kessie rolls the ball into the goal but Ansu Fati is adjudged to be offside in the build up.

The search for the opener goes on.

Pierre-Emerick Aubameyang is on the field. He joins Robert Lewandowski and Ansu Fati in attack.

Hold onto your seats, here comes the Barca charge!

Whoosh.

Robert Lewandowski spins and strikes the ball well but it flies past the post. That was the moment the Nou Camp had been waiting for.

He covers is mouth in disappointment. I have to say I was expecting to see the net bulge.

Barca look increasingly frustrated now as Rayo Vallecano continue to stand firm.

Pierre-Emerick Aubameyang is warming up but still no sign of his imminent arrival.

Robert Lewandowski hits the deck inside the area. The Nou Camp roars in appeal.

The referee waves his arms and it's no penalty. On we go...

Sergio Busquets is known for his reading of the game and his range of passing, but the midfielder lets one fly from just outside the area.

It's some hit and Stole Dimitrievski has to make a good save, diving to his left.

Still goalless.

Ansu Fati has been on the field a matter of minutes but he is already stamping his authority on the game.

Coming in off the left wing he's seeing lots of the ball and attracting several white shirts. He forces Stole Dimitrievski into a good save.

Talent.

Former Man Utd and Chelsea forward Radamel Falcao is also on up front for Rayo Vallecano.

Now then, Frenkie de Jong is stripped and prepared to enter the fray.

The Netherlands midfielder has been the subject of plenty of transfer speculation this summer, but he remains a Barca player for now.

He comes on to a loud ovation.

Rayo Vallecano are much more of a threat since the break and the game is opening up.

Surely it's only a matter of time before we see the opener.

Robert Lewandowski's shirt is almost pulled off his back and it results in a yellow card for Florian Lejeune.

Simple decision for the referee.

Nearly the deadlock broken, and it was Sergio Camello for Rayo Vallecano.

The forward is fed the ball in the area and he rolls it away from the goalkeeper but his lofted effort is just wide of the post.

Big chance for the visitors.

The second half is barely a minute old and we've already had a pause in proceedings.

Stole Dimitrievski is lying on the turf after a challenge inside the Vallecano area. Didn't seem to be much in that.

We're back up and running.

The players have emerged from the tunnel for a second time this evening and we're all set for another 45 minutes...
