El Clasico: Pierre-Emerick Aubameyang Stars As Barcelona Thrash Real Madrid

Xavi Hernandez said Barcelona's 4-0 thrashing of Real Madrid could be transformative for the club after their Clasico demolition at the Santiago Bernabeu on Sunday. Barcelona blew Madrid away as Pierre-Emerick Aubameyang scored twice either side of goals from Ronald Araujo and Ferran Torres. The match was billed as a test of Barca's progress under Xavi and they passed with flying colours, a humiliation of their fiercest rivals suggesting they are primed to challenge again for La Liga next season.

"It can change the dynamics of the present and the future," said Xavi. "We had lots of chances and we were much better than Madrid, far superior. We deserved to score so many goals."

Asked if Barcelona are back, Xavi said: "It can be. This is the right path."

And while the result might have little bearing on the title race this term, a defeat of this magnitude, at home, and against Barcelona, will cause serious reverberations at Real Madrid.

It will go down with other historic Clasico thrashings, like when Barca won 6-2 at Real Madrid in 2009 under Pep Guardiola or 5-0 at home two years later.

Questions will be asked about Carlo Ancelotti's future, with Madrid outplayed tactically and technically by Xavi's Barca, who were faster, slicker and, perhaps most worryingly, could easily have won by more.

"We played badly and I planned the game badly," said Ancelotti. "I am sorry for the defeat and I am sad. But we have to keep it in perspective."

Madrid were admittedly without the injured Karim Benzema and Ferland Mendy while there could have been a degree of complacency, given they kicked off nine points clear at the top of the table after Sevilla were held to a goalless draw by Real Sociedad.

But none of that will excuse a loss as
