The 4–0 scoreline, though it will not stop Real winning the league, will sit smugly alongside other modern triumphs; 6–2 (2009), 5–0 (2010), and 4–0 (2015).
But despite being over a decade on from the first of those conquests, this performance carried a flavour that was tactically, if not visually, similar. Proof that the Barca philosophy has been salvaged from the ashes by Xavi (Xaviour) Hernández. A philosophy which is still capable of dismembering teams as good as Real Madrid, Atlético Madrid and Napoli.
Like many things in football, it started with Messi.
