Also was gonna put out Mata's beast season in 2012/13.
Guys probably the best natural no.10 in the world personally, followed by Silva and Fabregas/Ozil. Iniesta is a different type of no.10 but is the superior player to those two as he'd probably put similar stats if he was the typical hole player.
Silva and Ozil(his Madrid days when he's on form) are the best no.10s to watch play though.
