The London outfit slipped out of the top four on Saturday as Everton won 1-0 at Sunderland, while they were in FA Cup action against Wigan Athletic at London's Wembley Stadium.
"I didn't even know the result and I think if we win our games we will finish in front," the Frenchman told reporters.
"For us it's important now to focus on the Premier League and if we do that well, I'm confident we will come back.
"On top of that we have a target now for the end of the season. We have a final in the FA Cup but we now have a period where we can concentrate on the Premier League."
Arsenal defeated Wigan 4-2 on penalties to book their place in the final of the FA Cup.
