Arsenal midfielder Mesut Ozil says they cannot relax after a flying start to the season.
The Gunners are top of the Premier League and have won their opening two Champions League group matches, with Ozil starting to show his class following a £42.4million move from Real Madrid.
Ozil said: "What's important is that we take the next step forward as a team. We want to keep developing. We did that against Napoli and won the game 2-0. We've got some great players in. We showed against Napoli how good we are on the ball."
