On Friday morning, as he does almost every Friday morning, Arsene Wenger will climb the stairs of Arsenal's London Colney training ground, a place he helped design some 17 years ago from the ashes of a fire.
On entering the press room, Wenger will walk past a colourised photograph of Woolwich Arsenal's 1913-14 team. Then he will take his place at the top of a room where three Arsenal portraits hang on the wall: Alex James, David Rocastle and Cliff Bastin. The theme will be 'History'.
Officially, the 20th anniversary of Wenger's arrival at Arsenal will be marked by the club on Saturday.
