From a quick look at the Reading messageboards, Piazon was played on the wing (when used), and wasn't too highly regarded by their fans - considered too lightweight. He seems to be something of a poor man's Oscar. I can't seem him being a regular starter; I'd expect him to be backup for the spots currently occupied by Kebano/Ayite, Cairney and Aluko - not quite in direct competition with Jozabed, who is more of a central player.
