Arsene Wenger may feel he has lost his X-factor... Arsenal must take their time over what to do with the best manager in their history

Wednesday night was without doubt Arsene Wenger's lowest point at Arsenal. Wenger is a proud man and will have been embarrassed by the manner of the defeat by Bayern Munich.

After the game he looked ashen-faced and I do not like seeing him this way. He is my footballing father. None of the managers I worked under cared for me as a player as much as Wenger.

In terms of trust, knowledge and care he was ahead of anyone else. When you have someone like that in any workplace you remain steadfastly loyal to them.

It will be a sad day when the decision is made for him to leave the club but the timing of his departure is dependent on if he and the board feel he can still take the club forward.

The recent performances against Watford, Chelsea and now Bayern were some of the least inspiring we have seen from Arsenal in a number of years.

In the last four seasons Wenger has not had to contend with losing a star player, such as Cesc Fabregas, Robin Van Persie and Samir Nasri in seasons gone by. He has been allowed to build this team without any disruption.

Arsenal's contribution to the Champions League in the last seven seasons feels very hollow. That he has not been able to strike fear across Europe will be one of Wenger's deepest regrets.

Wenger may feel he has lost his X factor and that the team has not progressed as he wanted it to.

The owners, the board and Wenger need to make a collective decision that is in the best interests of Arsenal football club.

This is a critical stage in the club's history and a decision cannot be made overnight. All parties must be given time to weigh things up.

There is another huge game for Arsenal on the horizon. Wenger is a fighter and will be thinking about nothing else other than beating Sutton United.

Whatever decision is made, Arsene Wenger will remain the most innovative, influential and successful manager in Arsenal's history.
