Bacary Sagna believes Arsenal have "woken up" in recent weeks and rediscovered their best form.
After a disappointing March, the Gunners won their FA Cup semi-final against Wigan Athletic and then claimed successive victories against West Ham United and Hull City.
The France right back was delighted with Arsenal's resolve in those games, and believes it bodes well for the run-in.
It was about time to wake up and that's what we did recently in our games. We're fighting a bit a more and we're helping each other a bit more as wellBacary Sagna
"I hope the best is still to come because we still have games to play," Sagna told Arsenal Player. "It was good to stick together because we were playing quite badly and dropped many points.
"But it was about time to wake up and that's what we did recently in our games. We're fighting a bit a more and we're helping each other a bit more as well.
"We had to react because we were beaten too many times and didn't fight to win those games. We showed a different image from what we've done in the past year and it was not Arsenal.
"Now we're fighting back and we will take it step by step. With Wigan we managed to show some character - it was good to come back to win the semi-final and I think it's going to give some power to the team to the end."
Arsenal will be favourites against an out-of-form Newcastle United on Monday night, but Sagna says they will still have to work hard for the three points.
"We have to win every single match and play it game by game to qualify for the Champions League and win the FA Cup," he said. "But it won't be easy because [Newcastle] will want to show a different image, they will want to take points and they will want to wake up like we did."
