Arsene Wenger praises Arsenal midfielder
"There was always a huge pressure on him to come back as quickly as possible and to expect a lot.
"He's on a good way in training. He's getting stronger and stronger every day, and that's what we want from him.
"He was injured at the start of the season from last season, so he was a bit behind the other players but he's getting better and better.
"Every game is an opportunity for him and this season's a good opportunity for him as well."
Arsenal have had a mostly poor start to their season, with a heavy defeat in the Premier League to Liverpool duelled with a poor transfer window fuelling supporters disgruntlement at the club.
