KP was in the team when Amjad Khan played his only test, wasn't he? Might've even played with Schofield when he was briefly recalled to the T20 squad as well. That being so he's clearly being way too harsh on wee JT.
Makes one wonder who the "senior player" is who confronted KP is too. My money's on Prior.
Whole thing sounds as if Pietersen has gotten too big for his boots. It'll be very interesting to see if he's offered a central contract or if he accepts one if he is.
