Wenger took the law into his own hands when spat on as a player

Arsenal manager Arsene Wenger believes trial by television is a positive development for the Barclays Premier League.  

And believes retrospective action should deter anyone from taking retribution themselves – as he did when spat on as a player.

Newcastle forward Papiss Cisse will serve a seven-match suspension for spitting at Manchester United defender Jonny Evans, who was on Saturday banned for six games after initially denying the Football Association charge.
