Arsenal boss Arsene Wenger is supportive of Portsmouth defender Sol Campbell's call for action against abusive fans.
"Why should we not be respected just because we are on the pitch?
"I agree completely with him. Most of it is abusive. But why do people get away with it? Because they are among a mass of people.
"I personally have a long and heavy experience of it. The best idea is to film them and then show the DVD to their family at home. That is the way to deal with it.
"They are entitled to an opinion. They can say to the manager "you are useless", but you cannot say "you are a f****** b******."
