#5 His experience can be a virtue
Wenger has been a head coach since 1984 and in football since 1969. At 68 year old, he has years upon years of experience dealing with players, staff and directors, and has seen many tactical trends come and go.
While young, well-educated coaches are currently in vogue, the experience can still be a valuable resource to call upon. If surrounded by a young and dynamic group of coaching and recruitment staff who are willing to challenge him, Wenger certainly still has a place in the modern game. He is naturally inquisitive figure and that needs to be channelled.
He doesn’t have to be as directly involved in all facets of the club as he has been over the course of his long tenure at Arsenal but used in the right context, his attributes and experience can still make Wenger a productive figurehead for the playing side.
