This is how Goal.com's Carlo Garganese describes Xavi and I am 100% in agreement...
"After a bright start from the English side, Xavi took charge of the centre of the pitch along with the equally brilliant Andres Iniesta, and dominated the play. Every single Barcelona move went through the pint-sized playmaker. He created Lionel Messi's goal, supplied the passes for Thierry Henry and Carles Puyol’s one-on-one chances, hit the post with a free-kick, and orchestrated the Spanish symphony."
"Xavi is quite simply a genius -the best centre midfielder on the planet. During the 1990s, Barcelona and Spain possessed another world class playmaking midfielder by the name of Pep Guardiola. It is fair to say that Xavi has now surpassed the man who has coached the Blaugrana to a league, cup and European treble in his first season on the Catalonia bench."
I think the best CM in Barca's history...
I recently read an article about Van Gaal's declaration before that "Xavi is better than Dela Pena (great MF at that time)." They had a good laugh at such declaration... but it turns out Van Gaal was spot on!
