All those years ago when I was in Tottenham's youth team, one specific spectator was guaranteed to attend the local derby.
You would see him standing on the sidelines at Arsenal's London Colney training ground, studying every kick and move.
I wouldn't say he had an aura but you were never in any doubt that he knew everything there was to know about football. His name was Arsene Wenger.
This was the late 1990s and he was relatively new to our country but I'll never forget how Arsenal's manager, regardless of how busy he was, would make a point of attending these games.
