Ramsey was the matchwinner for the Gunners in victory at Marseille this week.
"We haven't had the greatest of starts to the season but, hopefully, we've turned the corner by getting a few wins on the bounce and we want to keep it going," said Ramsey.
"There is no question our confidence is returning now.
"In past games, we could have defended better as a team and it was a bit harsh to blame it on the defence. I thought they did magnificently last night."
