Arsène Wenger has revealed why he has altered the way Arsenal defend corners this season.

In the opening few games of the campaign, the Gunners have opted for a zonal system rather than the more traditional man-marking organisation.

Last season, the statistics suggested Arsenal conceded a relatively high proportion of goals from set-pieces. Wenger is not certain to continue with the experiment but, tellingly, his team are yet to concede from a corner this term.

"Yes we have changed our system a little bit," said Wenger.  "It's too early to say that it works but the signs are positive.

"It has advantages and disadvantages. You need a great sense of individual responsibility with zonal marking. Taking initiative and responsibility is bigger.

"But it looks more rational. When you run after somebody, the players can cross each other and that can stop you from intervening. You are less subject to screening too."
