Arsenal manager Arsene Wenger has warned his players that they must not underestimate Norwich City when the two sides meet on Saturday.

The Gunners currently sit top of the Premier League, while Norwich are in the bottom three having lost four of their opening seven fixtures.

However, Wenger has said that his side must be switched on against Chris Hughton's men.

"At the top level, one of the keys is to switch on and off when it is right," Wenger told Sky Sports News.

"We have learned something in the last 18 months, that the Premier League has changed, that every single game is a potential danger for any team in the league and the recent results in the Premier League have confirmed that.

"Every team who are favourites today are on their toes because they know every game is a potential danger. It is always a potentially dangerous game to play Norwich because they are a team with a good dynamic and are not scared to play. They showed that against Chelsea in the last game."

Arsenal have won five of their last six league games.
