Wenger defended the professionalism of the Russian forward, who has returned to the club and is trying to win back the support of the fans.
"I have personally a great respect for Andrei Arshavin," Wenger insisted. "Sometimes some wrong ideas circulated about him -- that he doesn't care -- but it's completely the opposite. He's a 200pc professional who works every day very hard in training."
Arshavin (pictured) recently went back to Zenit St Petersburg on loan, but did not make a permanent move. Wenger said that only the quality of his team-mates was currently keeping him out of the Arsenal side.
"At the moment he's a victim of the high level of competition that exists for places. I think he has a huge respect from everybody in the dressing-room, and especially from the staff.
"We will give him, of course, some competition on Wednesday night. I feel he's unhappy he doesn't play because deeply he loves football and he practises every day with 100pc commitment."
Some players who have been in and out of the Arsenal team so far this season, such as Olivier Giroud and Theo Walcott, are likely to start, along with youngsters such as Ignasi Miquel, Nico Yennaris
and Alex Oxlade-Chamberlain. Emmanuel Frimpong, returning from a knee ligament injury, will be on the bench, further strengthening Arsenal's midfield options.
"If possible, we will put him on," revealed the manager. "It's a big moment because he has suffered for a long time and has worked extremely hard, like Jack (Wilshere). Physically, Emmanuel has never been as fit as he is now."
There should also be places on the bench for some of Arsenal's typically talented U-21 side.
Serge Gnabry, a lively German winger, has impressed for Terry Burton's team so far this season and may make the 18-man match-day squad.
"Gnabry is a great hope for the future," Wenger said. "I rate him highly. He had some injuries. If he continues his development, I think he could play this season in the first team." (© Independent news Service)
