Aston Villa legend Stan Collymore has called upon the English Football League, the Football Association and fans of other football teams to boycott Charlton Athletic.

The call comes after supporters of the London side received letters informing them of sanctions against their season tickets if they posted negative social media comments about the club.

Collymore, who left talkSPORT in July, played for the Addicks’ London rivals Crystal Palace for two years in the early part of his career and is incensed by the letters fans have received.

“Should be a full boycott of Charlton Athletic Football Club supported by the EFL, FA and fans of other clubs,” Collymore tweeted. “Let clubs take the p***, any clubs, and they will.”

The former Villa man also tweeted an image of the letters that Charlton have sent its more vocal followers.

The document highlights an imposed ‘Agreed Behavioural Contract’, meaning that fans are seemingly not allowed to post any kind of negative comment about the club on social media. If they do, their season tickets will be invalid.

Millionaire Roland Duchâtelet took over the club in January 2014 and tension between fans and the club have been high ever since.

Relegations have led to a number of protests from the supporter group, C.A.R.D, (Coalition Against Roland Duchâtelet) with the aim of forcing the Charlton Athletic owner out of the club.
