Better statistical models thus might take into account the correlation of interannual variations, or have explicit account of natural drivers (the sun and volcanoes), but will
quickly run into difficulties in defining these additional aspects from the single real world data set we have (which includes human impacts).
The drop to junk status shows that the company could
quickly run into difficulties in paying its debts, especially as the company will see its cost of capital increase and its financing options shrink as a result of the downgrade.
It's difficult to blame Ozil for the
difficulties he's faced at Arsenal without looking at the big picture... like the fans, he too was lied to by Wenger... there is no doubt in my mind that he was told by Wenger that he was trying desperately to recreate our earlier success by acquiring players that fit the system he
ran when Henry was in his prime... as we know this hasn't happened... in order for Ozl to flourish he needs some speed up front, forwards that can make intelligent
runs, a boss in the midfield to compensate for his obvious defensive liabilities and defenders who can transition from defence to offence
quickly and efficiently... much like he had in Real and with the German National squad... unfortunately he ended up on a squad that has a striker who plays with his back to goal, very few intelligent
runs into the box, minus Sanchez, no one to take pressure off him in the midfield, once Cazorla was injured, average defensive midfielders around him, which simply highlighted his lacking defensive qualities and defenders who lack the necessary cutting edge when it comes to transitional passing... instead of blaming Ozil, which is simply too easy, especially considering his mopey disposition, we should be asking ownership and / or Wenger why they brought him in if they didn't intend on doing what was necessary to get the best from him... can you imagine Ozil playing with the likes of Henry, Viera, Petit and Pires, it would be incredibly to watch and even more difficult to stop... so the only thing different between his experiences in Real and with the German team versus his time at Arsenal are the players around him and we all know who is in charge of making those decisions, the Grinch who stole soccer
Bratton seems to agree in his article, saying that in his experience, alternative fee arrangements
run into difficulty when projects «blow up
quickly or change direction unexpectedly, such that a quote at the beginning of a project based on a number of assumptions can become meaningless.»
