The topsy-turvy nature of Real Madrid's season continued on Thursday evening.

Only a week on from a demolition job at Anfield, defeating Liverpool 5-2, they were humbled in the first leg of their Copa del Rey El Clasico with Barcelona.

The final scoreline of 1-0 may not suggest they were too out of the game but the fact of the matter is that Barca were far the better team.

Leading LaLiga by six points and now ahead in the tie, it is Xavi's men who are undoubtedly having the better season.

Even if they are out of the Champions League and indeed the Europa League, few would have bet they'd be ahead of their famous rivals at any stage of the campaign last summer.

Embroiled in financial trouble and a mess behind the scenes, few gave the Catalan giants any hope of achieving success this term. Yet, they have defied the doubters and made another statement on Thursday.

Who was Real Madrid's worst player v Barcelona?

There were a few candidates for Carlo Ancelotti's worst player on the night with Eder Militao the unfortunate scorer of an own goal, Nacho dragged off shortly after the hour mark and Karim Benzema a lonely presence in attack.

However, the Frenchman's lack of impact on the game was arguably because of Vinicius Jr.

The Brazilian has been the main creative presence of Los Blancos this term, scoring 18 times and registering eight assists, but had no such joy this time out.

Indeed, he was "eaten" up by titanic defender Ronald Araujo in the words of one Barcelona source on Twitter, while The Mirror's Colin Millar stated that the 22-year-old was "totally locked down" on the night.

That clearly shone through in the stats with Vinicius losing possession a catastrophic 24 times throughout the encounter, completing just two out of his six crosses and ending with a pass success rate of 69% as a marker of his wastefulness in the final third.

With that in mind, it's hardly a surprise that Benzema failed to exert much influence on the game with his usual partner in crime being bullied by Araujo and co.

In truth, the tone for Vinicius' tricky evening began early on when a WWE-style scrap appeared to break out between the youngster and Barca midfielder Frenkie de Jong.

The pair grappled each other for possession of the ball before the former was shown a yellow card, his ninth of the campaign.

That caution means that no other forward has received more yellows across La Liga, the Copa del Rey and Supercopa de España this season than the £222m-rated talent.

For all of the incredible trickery he can provide, that ill-discipline needs to be ironed out sooner rather than later.

It is hard to criticise the 5 foot 9 ace for much this term but in a colossal game, he undoubtedly let Ancelotti and his teammates down as they lost for the first time at the Santiago Bernabeu in 11 months.

It's a night, therefore, that Madrid and indeed Vinicius will need to move on from swiftly.
