Arsenal boss Arsene Wenger can't see managers ending their touchline confrontations.

Wenger himself was involved in a touchline spat this season, when he shoved Chelsea manager Jose Mourinho during Arsenal's defeat at Stamford Bridge in October.

"Ideally, you want us to behave in a perfect way so maybe you'll have to build a wall between the two dugouts!" said Wenger. "The bigger the distance, the better it is. In the modern stadium it is much better.

"At the Emirates, for example, we have had zero incidents because we are far apart from each other. What happens when the dugouts are very close is that everyone speaks to the fourth official and then it becomes controversial very quickly. The incidents can explode in physical controversy. Overall, the distance between the two dugouts is a very important part of the peace."
