As usual I suspect that it's the press twisting the truth. But it's important to note that players know what works and most impostantly what doesn't work with them. I mentioned it numerous times because it's a high profile example but the case of Klose being unable to apply LVG's instructions on the field even he understood them on tape simply because he couldn't see the sequences on the field. People and some managers tend to forget that players aren't robots, you can't fully program or reprogram them to your ideas, you almost always have to make a step or several step in their direction. And it's also as important to know what they can't do or what they struggle to do than it is to understand what they can do. You hide the former and emphasize the latter.
Stop giving these players excuses.
