Amid suggestions that Arsenal attempted to sign Mario Gotze before the close of the transfer window, Arsene Wenger has indentified the Borussia Dortmund teenager as the north Londoner's biggest threat in Tuesday's Champions League encounter.
Several media outlets claimed Dortmund rebuffed an offer of £35 million from the Gunners for Gotze, who continues to make waves for club and country.
Arsenal were instead forced to focus their attention on signing Mikel Arteta and Yossi Benayoun as Wenger trawled the market in pursuit of midfield reinforcements.
Gotze, 19, will now have an opportunity to show Arsenal what they are missing out on, as the Bundesliga champions host Wenger's side in Group F of Europe's elite club competition.
"He is the provider," Wenger told the official Arsenal website. "He is the one who had the best assists in Germany and is the most dangerous player.
"He links well with his strikers and is the player we have to keep quiet. The best way to keep him quiet is for us to attack."
Arsenal will be without Aaron Ramsey and Tomas Rosicky at the Signal Iduna Park after both were ruled out through injury.
