According to Tomas Andreu of Sport, the French manager is unhappy with the Gunners' recent results and wants his players fully focused on improving performances, and thus, he has barred the likes of Santi Cazorla, Hector Bellerin and Mikel Arteta from speaking to the Spanish press.
Who will qualify for the last eight of the Champions League?
Andreu noted that Wenger's newly tightened media policy is "to avoid any distractions before the game," with many outlets having requested access ahead of the Barca clash.
Arsenal have been knocked out of the Champions League at the last-16 stage in each of the previous five seasons, hardly a good return for a club that purports to be one of the best in Europe.
In back-to-back tournaments in 2010 and 2011, the north London outfit were knocked out by Barca, a fate that many believe will befall them again in the coming weeks, per 90min:
The respective form of the two sides has done little to allay such fears.
While the Gunners have started to struggle, Barca have continued to devastate opponents, winning their last nine matches in all competitions.
If Arsenal are going to have any chance of knocking the Blaugrana out of the Champions League, they need to re-find some form in the next three matches.
If they go into their first leg against the European champions with the form they are currently in, they will likely be turned over, a situation Wenger is clearly looking to avoid, hence his latest media tactic.
