"He over-reacted in that match [four years ago] but this is a good opportunity to show he has matured," said Wenger.
Tonight's game has already been overshadowed by the prospect of Sunday's Premiership meeting with Manchester United at Old Trafford and the war of words between Wenger and Sir Alex Ferguson shows no sign of abating.
Following Sir Alex's assertion that Arsenal "got away with murder" with the punishments imposed by the Football Association in the wake of the ugly scenes that followed the goalless draw between the sides in September last year, Wenger was not slow to respond.
"I think he has a sense of humour," said Wenger. "Maybe he thinks it would have been better to have us put against the wall and shot."
Henry and Robert Pires have more immediate concerns however, as they prepare for tonight's clash. Pires has been given the support striker role in place of absent Dennis Bergkamp - a position that many feel he should fill with France now that Zinedine Zidane has retired.
