Rangers were without the injured Craig Moore, RonalddeBoer and Steven Thompson for their first appearance in the Champions League group stages in three years.
Dutch coach Frank Rijkaard has injury concerns over both RonalddeBoer and Edwin Van der Sar, who are fighting to be fit for Sunday's clash with Yugoslavia.
And after RonaldDeBoer blazed a penalty over following Gilles Grimandi's foul on Tottenham's Edgar Davids - the day's pantomime villain, Kanu's deflected shot made it two to Arsenal.
Rangers responded with Shota Arveladze slashing a shot wide from edge of the penalty area and RonalddeBoer made a mess of a header at the back post from a Neil McCann delivery.
