You cules tend to overrate him though. He deserves top-23, sure, but he's not as spectacular as he's made out to be. In other words, he's 100% critical for your system and for Xavi & Iniesta to perform as they do. But I don't think he'd fit as much in other gamestyles.
Don't forget that Messi is nothing without Xavi&Iniesta also, Pique is the most overrated CB in the world, JA and DA don't know how to defend, Valdes is useless and this Barca team doesn't need a coach.
To quote a wide, stocky but not fat Milanista, Busquets is "underrated by most, overrated by Cules, but actually somewhere in between."
This quote is better: "the current Barca squad can have so many mediocre players that slip under the radar due to Xavi-Iniesta-Pique-Puyol-Messi..a bit like how Pavon looked imperial when Hierro and Makelele was there, ditto Helguera."
And by any chance, are you talking about the same cules who wanted to sell Pique, Dani, VV or Pedro last year, who needed 2 years to accept that Yaya was sold because of Busquets and are criticizing their coach even when their team had the best start in the history of La Liga?
I'm just happy that Busquets is aprecited by people like Pep, Vdb or Menotti and his teammates cause in the end that's all that matters.
