After his cameo against Barcelona, the Englishman was hailed for his performance. But ahead of Saturday's game against Wolves, Wenger said that Walcott wants to be more than just an influential substitute.
"I believe at a certain stage of your career you can be an impact player but the target of Theo is to become a regular player," he told arsenal.com.
"He started the game at Birmingham and he has a good chance to start the game tomorrow.
"These kinds of games you win with a squad. Most of the time the battle is so hard, that after 70 minutes when the level drops a bit, players who have quality can come on and make a difference."
