The pillar on which Xavi Hernandez will build his Barcelona project

The history of the clasico will always have this 0-4 stored on the hard drive of its memory. In the image and likeness of that 0-5 with Johan Cruyff on the pitch or the 2-6 with Pep Guardiola on the bench. It's a result that, due to how it was produced, will become the pillar on which Xavi Hernández will be able to build his project at Camp Nou.

The path is marked: it's what we saw on Sunday at the Santiago Bernabeu. If Barça are capable of always playing like that, they will make history. In addition, supporters needed an injection of happiness like this, a shot of pride and optimism. Beating Real Madrid at their stadium, hammering them, bettering them tactically and physically, make up -- although only a little bit -- for the frustrations of recent seasons.

HAY LIGA? It's a shame, honestly, that Barça's extraordinary reaction has arrived with the league in the final stretch. But there's no reason to lament that. Before Xavi arrived, the circumstances and the squad were different. The club gave him the players he needed in January and that, with hard work and a tactical plan, has produced another Barça. Nothing is impossible and if Barça beat Rayo on their game in hand, the gap to Madrid will be nine points. The shitting-yourself-metre? We will see...

CHARACTER. With Xavi, pressure is non-negotiable, as is possession. They are the keys to the identity that have made the team recognisable. The performances of the new signings should also be applauded: Aubameyang, Ferran, Adama... The team is true to its philosophy and that allows it to be recognisable. We saw as much at the Bernabéu. They scored the first goal and went for the second and so on. We are seeing an ambitious Barça, hungry, non-conformist, that presents its candidacy at very high levels. Defeating Madrid at the Bernabéu and giving them a real football bath is proof that the great Barça has returned.
