Arsene Wenger has backed Sol Campbell in the campaign to tackle crowd abuse - and has called for the perpetrators to be named and shamed. Portsmouth centre-back Campbell, who faces his former club Arsenal on Boxing Day, believes the vitriol from supporters is now a human rights issue. Wenger also has a history of getting taunted by fans and insists there is a line that should not be crossed. 'Fans are entitled to their opinion,' said the Arsenal boss. 'I have a long and heavy experience of being abused by fans so I know what I talk about.' Celtic boss Gordon Strachan is another figure who has spoken about the problem, while Norwich manager Glenn Roeder has described guilty supporters as 'low lives'. Pompey boss Harry Redknapp was also subjected to unsavoury chants at Aston Villa. Campbell wants the Football Association to address the issue. Wenger added: 'Sol has a big point. Why should you not be respected just because you are on the pitch? I agree completely with him. 'Why do people get away with it? Because they are masked by being around lots of other people. 'If they did it individually, you could see who to target. I feel the best is to film them when they shout abuse and then send the tape to their family so they can see what is going on. That is the best way to combat it.'
