100% agree on the above but at this part of the conundrum I would point the finger at the board who have offered him the new deal.
I think we would both agree that Wenger probably believes he can turn this around so will sign, but that option perhaps should not even be available to him, the board having weighed up past years, past failures and decided that all in he has done a great job in the far past but is not the man for the future.
The whole scenario is at risk of descending into farce from boardroom level through management to playing staff. None of these three seperate parties are coming out of this with one ounce of credit.
