Wenger hopes the 32-year-old can repeat the influence he had last season.
“He had a great impact last year in our comeback from February until May,” Wenger said. “Hopefully he’ll do that again this season.
“Unfortunately we lost him during the European Championships. He’s just back to full fitness now I believe.
“Hopefully he’ll help us because we have many games coming up and I’m convinced he will be a big help, because he has technical quality and his mobility is important in the way we want to play.”
