A year ago Wenger took control of a club in turmoil. Because of the scandal which brought about George Graham's departure, his immediate successors enjoyed far less control, but Wenger's arrival restored the power balance.
"For me the basics of the job was to have the freedom to run the club as I chose - to make the important decisions about what was to happen inside the club, to buy the players, to sell them and decide on things such as contracts and even a new training ground," Wenger said.
"Without an assurance of that freedom and control I would not have stayed. Maybe you are used to that in English football, but in some foreign countries the manager can come back for the start of the season to discover who the president has bought and sold during the holidays."
Arsenal, seeking to overcome a 1-0 deficit from the first leg, have Lee Dixon fit again and expect Ray Parlour and Marc Overmars to shake off knocks.
