Former Newcastle ace trolls Sunderland fans on Twitter

Joey Barton knows a thing or two about the Newcastle-Sunderland rivalry.

After the dismissal of Paulo Di Canio as Sunderland manager, Barton took to Twitter to share his thoughts about the North East club's decision.

Safe to say Barton, who played in Newcastle 5-1 demolition of Sunderland in the Tyne-Wear derby at St James' Park back in 2010 had no sympathy for the Mackems.

He referred to the club as 5under1and, in reference to that famous win for Newcastle on Halloween - and even mocked the city as a "cultural utopia".

Here are a few of Barton's tweets:
