7 legendary coaches who did not have great playing careers

#3 Arsene Wenger

Wenger's legacy at Arsenal will always be remembered

A true revolutionary of the English game, Arsene Wenger is the greatest manager in Arsenal's history and one of the greatest of all time, having led the London club for 21 years in a period of never before seen success, while his insistence on monitoring players' diets, introduction of scouting changes and training regimens helped improve the global standard of the game.

Till date, he remains the only manager in history to have finished a Premier League campaign undefeated, having guided his invincibles side to the 2004 EPL title without losing a single match, while he is also the manager with the most FA Cup wins in history.

As a player, Wenger did not do too much of note, playing as a midfielder for amateur sides such as Mutzig and Mulhouse as well as Strasbourg to not much success, only making 80 appearances throughout his career.
