If Barcelona wanted to prove their resurgence under Xavi should be taken seriously, then they should have silenced the Bernabeu and then rekindling the magic of El Clasico after a period of Real Madrid dominance.
The Catalan giants have been reborn under their legendary former player and after Sunday&s historic and emphatic victory against the La Liga leaders it looks certain Xavi will only further that legacy.
After the visitors completed a dominating four goal victory over their oldest and fiercest rivals, veteran defender Gerard Pique took to his verified account to say that they were back.
That was poignant coming from a man who has experienced more Clasicos than most, through the intensity of the rivalry between Lionel Messi and CristianoRonaldo, under the highs of the mesmerising side, and more recently during the upheaval caused by the financial struggles of the club.
Real Madrid will celebrate their 35th title with their fans at the Cibeles Fountain in the heart of the Spanish capital come the end of the season.
Barcelona have now set the tone for the future of this classic encounter, as they are now nine points clear of Sevilla and 12 ahead of Barcelona at the top of La Liga.
Xavi said that the negative dynamic of losing the last few Clasicos was changed.
I don't know if we can win the title. We can not rule out anything. Maybe we are a bit late but this is a big win for us.
I am very proud of my team. This can help us going forward. There is still a lot to be done.
Since arriving at Barcelona in November, Xavi has been able to quickly implement his desired style and has been boosted by what now look very shrewd signings in January.
The former Real Madrid and Barcelona player said he was not surprised by Xavi's potential as a coach.
You could already see that he had the ability to understand how complicated coaching is for everyone. He used to position the players in front of him in a way that he saw them. You can already see things.
He has changed the face of Barcelona. The signings have been important. The signings that have come in this season have helped the team.
We have to be patient with him, but I think he is the right coach because he was born at the club, he has the Barcelona philosophy, and he has everything to be able to succeed at FC Barcelona.
The new signings include Pierre-Emerick Aubameyang, who stunned the home fans at the Bernabeu into silence when he headed Barcelona's first and then sent some heading towards the exits when he grabbed his side's fourth after just 51 minutes.
The Real supporters had to suffer the ignominy of listening to a small pocket of travelling Barcelona fans, with Pedri and Gavi suggesting they can be key components of many El Clasicos to come.
Spanish clubs have been really good and people were saying that when Messi and Cristiano left.
The Super Bowl is the marquee fixture of the La Liga and they have been trying to make it more special by hosting pre-match parties with celebrities and staging fan events across the city.
After three years without a win against Real, the marketing for them has stopped.
In the days leading up to El Clasico, cranes and construction vehicles continued to work inside and out of the Bernabeu as part of the futuristic renovations on Real Madrid's famous old ground.
It looked like the team's confidence may be in need of a little support as they looked on at the end of a cold Sunday night.
The club has been searching for a replacement for the departedRonaldo and Hugonchez hopes that the signing of Kylian Mbappe from Paris St-Germain will solve that.
The expectations Madrid fans have is that he will sign, he is the most attractive player in the world.
The trophy room at Real Madrid, his branded gyms around Madrid, and his own Pestana CR7 hotel on Gran Via are all reminders of how much he means to the city.
Vinicius Junior is the current poster boy for Real Madrid, and he proved on Sunday that he will also be a star for Los Blancos.
He has a lot of potential, a lot of individual quality, a lot of technical quality, and this season he is learning more and more about Spanish and European football.
He is a player that I like a lot because he has a lot of personality, he faces one on one, and he is the Vinicius I saw in Flamengo, the one-on-one, the individual quality.
Real will need Vinicius and any incoming stars this summer to help them compete with a Barcelona side who will challenge more strongly for the title.
Domagoj Kostanjsak, a sports journalist and football analyst who covers Barcelona, says he is confident that Xavi's blueprint guarantees them a foot in every league game.
Once they upgrade certain positions, they will be well on their way back to the top.
