I mean like a coach in charge of all the footballing matters under Wenger's watch who focuses on little bit of everything. The coach free of other responsibilities about clubs finances and all that. Transfers too may be. Like how it is at Bayern or Barcelona. Coach has a say on transfers in terms of advice and player profiling but mostly focused on the footballing matters rather than anything to do with how the club is run.
And I believe first team coaches need to change frequently in 3 years.
I think it is actually a huge problem today with modern managers that they are not allowed to fully express them. Manager need space and time to implement their ideas. It is totally lacking in today climate.
But you are probably right, hence I will most likely be off football when Wenger quit.
