This train of thinking is a double edged sword.
If you say that it's Ole responsible for transfers (getting rid of deadwood, not going into panic buys), then he has to be taken fully accountable for the state our current squad is - short to the bone and little to no bench.
In terms of getting rid of the deadwood, LvG got rid of more deadwood in his first season yet no one really is trumpeting on that achievement.
He got rid of Buttner, Bebe, Welbeck, Anderson, Kagawa, Macheda, etc..
Not replacing the senior players he got rid of is not something I'd call big achievement, especially if he doesn't produce in terms of results - quite the contrary.
Also calling Maguire, AWB and James a big success is very premature on the back of 4 games. Matic looked great the first three months and look how it went. Martial looked like potential Ballon D'or winner and look at him now.
