Huge penalty call from Real Madrid as Vinicius Junior goes down in the box, right in front of the increasingly frustrated Real ultras.

The ref says no penalty, much to the dismay of the Bernabeu.

Just moments before Jorge de Frutos' equaliser, Kylian Mbappe believed he should have won a penalty for his side.

The Frenchman appeared to be pushed in the back by defender Andrei Ratiu after making his way into the box.

I'm sure they'll be plenty of conversations about it post-match if Madrid are unable to pick up all three points against Vallecano.

What a goal for Rayo!

They cannot believe it! Their small section of fans in the Bernabeu are jumping up and down in disbelief!

Whatever their manager, Inigo Perez, said in the dressing room at half-time has worked wonders.

They've started with the exact momentum Real needed to.

Vinicius Junior’s goal in the 15th minute gave Real Madrid a huge surge of momentum.

They followed it with an excellent 15-minute spell, creating numerous chances as Rayo struggled to string any possession together.

The final 15 minutes of the first half slowed in tempo, though Brahim Díaz missed a golden opportunity to make it 2–0 against the visitors.

Los Blancos are whistled off at half-time.

The supporters want more - they're playing against a team that's 17th in La Liga and know the scoreline doesn't reflect it at the moment.

Let's see what the second-half has to offer...

Vinicius Jr's sixth goal of the La Liga season is what separates the two sides at the break.

Vallecano are afforded the opportunity to break after a slack pass from Dean Huijsen.

In the end, Real Madrid are let off the hook as the shot is blocked.

Three minutes of added time at the end of the first half.

It should be 2-0!

Brahim Diaz only has the goalkeeper to beat but he tries to slide the ball across the face of goal to Kylian Mbappe - Pep Chavarria is there to intercept the attempt.

How costly could that prove to be for Madrid?!

Vallecano are upping the ante as they look for a way back into the game. This time it's defender Pep Chavarria's with an effort that sails high and wide over the crossbar.

Alvaro Garcia strikes his effort from range straight at Thibaut Courtois.

It's a half chance at best for Vallecano, but something to build on after a difficult 15 minutes since Madrid's opener.

Vinícius Jr's afternoon may have started with receiving boos and whistles from the Real Madrid supporters - but he is full of confidence right now.

The Brazilian has just plucked the ball out of the air with an extraordinary bit of skill, before nearly working an opening for Brahim Diaz.

He has been at the heart of nearly all of Madrid's attacks this afternoon.

Reminder that Real Madrid haven't dropped points when scoring first in La Liga this season - winning all 15 matches.

After Vinicius Jr's early strike, will the home side be able to continue that run?

You can't help but feel the only way Rayo can get at this game is on the break.

Real Madrid are on fire and the momentum is firmly with them at the moment.

Arda Guler goes close to doubling Madrid's lead. The attacker evades a helpless challenge from a Vallenaco defender before forcing goalkeeper Augusto Batalla into a strong save.

Madrid have the wind in their sails after Vinicius Jr's opener.

For a moment, you thought Vinicius Junior might be doing too much with the ball. But there was only one thing on his mind: getting it into the back of the net. A brilliant finish. He sprints toward the fans, kisses the badge, and urges them on. Any doubts about where Vinicius Jnr's loyalties lie have surely been put to rest after that.
