Not sure I buy those examples - some like Clyne, Mané and to a lesser extent Jrod have performed exactly as expected. Others were bought when they were raw but had bags of potential; while others had outgrown their various clubs and we simply gave them a bigger platform on which to perform. By contrast, Martina is a journeyman, an established pro with a middling track record. I think it'll be very much a case of what you see is what you get.
